Discovery never calls and tries to push their clientele away

I've tried to contact discovery on many occasions. My wallet was ****** during April of last year 2020. I struggled to get through to have it blocked and have a new card issued. The charges on the card since the account is clean is 50 rand and I don't mind paying the fee. The issues are as follows they never called me to it replaced. I called them at least 8 times and the phone line disconnected and no one called me back. I have sent numerous emails to call me back. I could not pay the card as I had it saved as a card not knowing there is a different way to add them via eft. No one called me about the card and I couldn't make payment via three banking apps as the card expired. Yet no on called me. Then when I called in the last time the consultant advised the card or account should be migrated from fnb to discovery. No one told me I was overdue. No call what so ever. Then they advised to use the app. The app had an error each time and then the consultant advised I should pay the amount given I paid the account still the app didn't work then a new consluatnt which I had to call in again advised the account is in collections so no called me to advise pay it this way and replace the card.
