Poor service

Telkom took debit order of R4000 (normal R500) and Im told to wait until they done with ***** case, to refund money.. This can take forever with them. What can I do?

The data sim was ****** with the phone. Went to telkom store to report as ****** and to do sim swap. Store said no, line shows that sim swap unavailable. They logged so many cases and I received 5 sms that it has been cleared. With the first sms, I went to store and they made me do finger print and everything for sim swap. Then got told in store that they can not give me a sim. I have to wait 72 hour again. After that when I went back to store, suddenly there was a outstanding amout of exceeded money R7000 I as told. I have a suspicion that it was done in store. I had to fighting anf go to another store just to get the line suspended, so that they can stop doing ***** and steel money. The data sim I was told when I opened it, that its a top-up. Now Im told there is no such thing, all lines are open lines. I never had any issue with the data sim going over in an billing amount when data was finished. Why when I went to telkom store to report ****** sim, why then suddenly open line and money exceeded? How and when will I get my money back? Every time I called customer care I was told case logged, wait 72hours. Now Im told, its been handed to financial department and I have to wait. Its been more than a month..
