NO SECURITY ON STORECARD,BAD SERVICE

My RCS Storecard was approved in November 2021,made some purchases on it and paid my first installment together with the initiation fee.To my dismay,at first they could not locate my payment made via my Standard Bank EFT account.After numerous calls,they finally informed me that they located the said payment.My last transaction was at Sitari on the 21st of December.On the 27th of December2021,i went through my account via the app and noticed that ********** purchases were made at stores in klerksdorp,Newmarket and Hyde park,wherever this might be.I'm in possession of my card,NO NOTIFICATION of these purchases made came through on my phone.On the same day,i tried to contact this RCS,it took me half a day to finally made contact with their so-called ***** dept,only to be informed that i need to go to Game to fill in forms and to get copies of my card as well as my id.DONE THAT,WAS TOLD THAT IT WILL TAKE UP 21 DAYS TO INVESTIGATE.How did this ********* get hold of my card??how did her/she knew about how much credit there was on my card??Off the record,when i reported this incident to the police,they immediately suspected an "inside job"I reside in Stb,and according to the police,these stores where the purchases took place is all situated in Jhb.How is it possible for a store to approve transactions in the region of 30000.00 rand without checking for id/proof of address etc,etc.but when i purchased goods at Checkers Sitari,for just over a R1000.,i was asked for my id and received notification on my phone of the transaction.Inside job?????
