Discovery Bank **** and useless service!

This is probably the worst business i have ever dealt with. Firstly they've been charging me for a card that i cancelled last year. Secondly i've called their call center over 10 times to log a complaint and get the matter resolved but to no avail. The promise is the same..'Ï will escalate it to our supervisor and they will get back to you''. Guess what they never do! I sent messages on their platform for them to call me back and have received ZERO response. I tried cancelling the card through the discovery app. ZERO Feedback. I called their call center and was on hold for over half an hour before i hung up! ZERO response again. This bank is beyond useless! This bank is like a really bad **** that takes your money!
