Please investigate my ***** query and refund me

On the 13 & 14th Dec2024 in the evening and early morning, my RCS Mass build credit card was de*****ed close to R6 000, which I reported to RCS ***** department and their feedback was that I am liable for the purchases and that it’s not *****. The purchases were from BlueLabel Connect, which works on subscription and RCS is aware that I am not subscribed to. But they still not investigating further and paying back my money. The weird thing is I have not made any purchases on my card for the whole of 2024 and so I called RCS on the 11th of Dec 2024, Wednesday for a settlement letter....and BOOM on Friday my card is used for buying expensive airtime and RCS turnaround and says it’s not *****...the **** how? I didn’t lose my card, and I did not give my information to anyone. Please analyze my account, pay me back my money and let me settle my account.
