Shocking Service from Discovery Bank

I have recently received a really poor experience from Discovery Bank and I'm not even a client- 2 SMS's notifying me:

1: My discovery Vitality Device Booster rewards have been paid into a Discovery Bank Account, where it has always been paid into my savings account with another bank for the past 3 years-I don't have a Discovery Bank Account, now I believe they migrated an old Discovery Credit Card that I never activated(app**** for 15 May 2017).

2: Today they deducted a R500 debit order from my savings account. I phoned the call centre: Their response-They migrated the old Discovery Cards -previously underwritten by FNB and seemingly are now deducting money for a card that was never activated.

My Question: Who gave them permission to change the bank details of my Vitality Rewards deposits into a bank account that was app**** for 3 years ago and never activated, as well as a R500 debit order. These guys are off to a rocky start. I'm a loyal Discovery client-My short term insurance, life insurance, medical aid all with Discovery and now this-Unacceptable Service-Best of it all-You phone them and get told that they will log a call and get back to you in 5-7 days-Shocking!!!!!

I expect a call back tomorrow morning from a manager at this bank who is hopefully going to resolve this matter immediately.
