If you want to join a bank, use a different one

I have been calling the call centre since last year to fix the error on the discovery app that it won’t proceed for me to access the app. Since there is no other way of communicating with this bank, it is also frustrating. Everytime you call they promise to sort it out but it never gets done and it never gets followed up by them after so you have to keep calling back and explaining the same problem again and again like it’s Groundhog Day. I have numerous case numbers but no one has ever followed up. Your service is atrocious
