- [R2] Amex Excellent: This is by far the best banking app. It has the cleanest interface and the most responsive staff.
- [R4] Amex Control was taken away!!!: Even though the app gives users the option to control secondary authentication, and I chose not to enable it, American Express overrides that choice and forces secondary authentication anyway. That is unacceptable!!
- [R16] Amex Why change?: This was much easier and cleaner looking prior to this way now you don’t know what’s paid or not, simplify it for idiots like me! This app is awful
- [R18] Amex Let’s find a way to mess up a good app…: Horrible update. Used to be able to see what bill needed to be paid. Now it’s stupid icons and you have to open each transaction.
- [R1] Amex Trying to resolve a disputed claim: The CS experience awful. You can only text them not knowing if you have reached a real person. You can’t talk with anyone in the the department that handles the claims. I sent a fax and asked if it was received and was told they have no way of reaching that department.
- [R6] Amex Does not provide customer protection like before: Amex have the best customer protection and customer service is bar none about 5 years ago , amex does not provide customer protection as it used to
- [R7] Amex American Express Keeps Your Refund: Beware of Missing Money: I’ve had a very disappointing experience with American Express. Whenever I purchase items using my American Express card and later return the goods, the refund is supposed to go back to my card. However, American Express never returns the money, and I have to chase them down to get it. Even though the store has fully refunded me, it seem
- [R9] Amex Timing of Payment to Go Through: A payment was made about a week ago and my payment is still pending and I am unable to use my card because it was used to the max last month.
- [R13] Amex Do Not Care About Customer: I am simply a number. Decreased my limit twice over the past week. I was told the first time this was based off “their number calculations”, although I’ve never missed a payment in my 12 year history. Say my balances are too high. Lower my limits, lower my credit score, decrease my ability to recover and my feasibility to live. That credit line went from $6800 to $1000
- [R20] Amex Eligibility code for lounges are bull: Tried the code at the London centurion lounge they said that code doesn’t work. WHATS THE POINT OF THE CODE IF ITS NOT STANDARDIZED. I didn’t get into the lounge I did everything right got my code right when I entered the airport
- [R22] Amex Up and down limit: Stop raising and lowering the limit. Have you not ever got paid ? These cards may work one minute but not the next.
- [R3] Amex Improvements Review to get 5 Stars: American Express is a great company, But I think referral should be available year-round For all eligible card members, regardless which card they have, instead of limited periods. Also, I’d like to see a higher APY on the High-Yield Savings to be more competitive with other banks.
- [R8] Amex The best customer service: Love Amex! The difference in customer service is night and day compared to any other credit card Hands down the best I have several Amex cards but just received my business cards. Every expense from every employee is now dialed for easy accounting. Amex will always be the card available
- [R10] Amex Bad card to use for business: I used love American Express Platinum business card and used it for most of my business use. But for last 2 years this card become one of the worst cards . High annual fee and we can’t even use it as needed . I will close this account as soon I have paid off the balance .
- [R11] Amex Best card out there: So many points earned is paying our vacations great card to have.
- [R27] Amex Best app in banking: Always have a great experience using the AMEX app whether it is daily tasks or navigating something new. It is always a frictionless straightforward experience.
- [R64] Capital One Mobile Horrible, buggy app: Capital One is too big of a company and in way too many people’s business to have an app this buggy and unreliable.
- [R73] Capital One Mobile Buggy and poor design: I can’t authorize my card because capital requires thru their app that I still can’t properly access due to it crashing and freezing. I’be reloaded rebooted etc. Nothing works
- [R82] Capital One Mobile Always crashing: App always crashes after a bit, is slow to load or laggy. Please fix
- [R119] Capital One Mobile “We hit a snag”: I can’t imagine a worse app. Whenever I need this I get hit with an error on the splash page saying “we hit a snag” and with no way to access my app. I have tried updating, quitting and restarting… sometimes it just isn’t working. This is a real problem. I estimate the app works 10% of the time. I have been hit with late fees multiple times because of this. Buyer beware. I am
- [R63] Capital One Mobile Kept denying payments: Tried paying for optional cruise tours and paymentskept getting denied.
- [R69] Capital One Mobile Credited: My issue is that I feel that it takes relatively way too long for the payment process in the delivery and accessible credit to your account and really isn’t making any sense and it hinders me to pay bills when the delay is so long and strenuous
