***** on RCS account

Good day, on the 6th of January I called RCS because I noticed that ***** had been taken place on my account. I spoke to a consultant in the ***** department who told me that my account would be blocked and that I should complete a dispute form at a Game store. The following day I completed the necessary forms at Game as well as a police affidavit that was sent to RCS. I havent heard back from them since. I tried contacting them a few times holding on for 20 to 30 minutes at a time without getting through to anyone which is ridiculous. When I checked the RCS app the other day another return was done on my account on the 14th of January...how could this be if my account was blocked...should that not have been flagged when the person did the return? On top of that I received a statement for over R2000 that they expect me to pay for items I did not purchase. The ***** took place over the December period with purchases that amounted to over R30 000...RCS I want answers as to what is happening with the investigation and why my account wasn't blocked.
