Standard bank ***** division not crediting my account after I immediately cancelled cards when suspicious transactions were going off my account.

On the 22 June I noticed sms's coming through of 2 debits for Uber eats. I immediately phoned and cancelled all my cards to avoid further debits and have Standard bank reverse the money. I am still waiting for my account to be credited with those 2 amounts. I only get an email where they say they acknowledge receipt of my email and if I require assistance to respond to email which I do just to get another email a few days later saying the same thing. All I want is my money back in my account.
