Worst/ no service Discovery bank

Worst customer service ever!!!! I recieved a notification that I quilify for a credit card with discovery bank! And thought that I will use the account as an extra savings acount as the interest on a positive balance is good!!! The appication process went fast and I submitted all the documentation that they needed via the app and it was received by them! And this is where all communication from them ended!! I was told I will have a responce within 24 hours and to date nothing!!! A week after I submitted my application I phoned them and asked what was the delay and was told I will get a responce within 24-48 hours!! I waited another week and spent another hour on the phone being transferred from one department to another eventually being told that they can't can't tell me how long a approval is going to take and why it is taking so long... 4 weeks singe my application was submitted and still nothing!!! Not a yes or no!! Not a sorry but we do not want you as a client. NOTHING!!!! I am very disappointed with the service to date...
