Appalling Service/ ********** Transactions

I Received absolute appalling service from this bank, I had available balance of R31000 on the 1st of Oct on my credit card however when I checked my balance on the 22nd Oct I suddenly have a balance of R20,000, spoke to Thabile Mavundla who advised that there was a rebate on my account, and has escalated the issue I will only get feedback after 7 days, their complaints department doesn’t even have a number for me to call, she was using company jargon and not explaining what exactly happened to my 11k, I spoke to the team leader who is very arrogant, disrespectful and lacks client service, he is in a leadership position but Thabile was way more corporative and assisting than him. Call cut after I have been on the line for more than an hour and he didn’t even bother calling back. They can’t even explain what happened and just assumed I got extra funds which I used, I have to say following the ***** incident that took place months back on this account I would NEVER advise anyone to take credit with this bank, ***** and unexplained transactions take place on your account without your knowledge u need to go online daily to check your balances. The service is extremely poor, their people are uninformed and lack empathy, zero respect for their clients. I need feedback ASAP I need to pay this credit card on Wed but they can only give feedback in 7 days utter nonsense they lack sense of urgency even. Transactions take place on your card but they cant explain, even duplicate transaction they busy fidgiting your account in the background I even believe its their staff doing *****.
