Reverse funds back into my account

So last month l paid for my Dstv on the 26th of July, confirmed and approved one payment. But 4 payments went off. I immediately contacted the bank so they could advise and reverse the funds, only to get told l needed to get Dstv to reverse the funds, fair enough. Contacted Dstv and they only received one payment. So went back to FNB since clearly this is an error from their side, l got sent from one department to another, got told it was a digital error as all payments went off at the same time and funds would be back in my account within 24-36 hours. Got a reference number and after a week nothing happened so l contacted the bank again. The agent y l spoke to didn't know what l was talking about as the turnaround time is 7 working days. So that's 2 days more right so l waited, nothing. Called again then this lady says no its not 7 days it's 30 working days. What the hell? So l speak finally to someone in the digital complaints department, and this lady says your case is still pending, l will get someone from the admin to give you a call ASAP and guess what l am still waiting for that call. Is it too much to ask for that money back into my account? To get a simple feedback on what happened?
