RCS and Game *****ulant Purchases

On Monday 22 October while at work, I received a SMS that there had been a purchase for R4870.00 made on my Game store card. I immediately contacted the number provided on the SMS and was advised that there were in fact purchases made at Edgars . I was put on hold and the agent blocked my card immediately. Firstly, how is it possible for another individual to make purchases on my account as authorization is required. How was this authorized when my ID, drivers license and store card was in my possession??? I then had to Game Mall of Africa where i was told by the consulatant that i need an affidavit from the police station and then to take it to a branch or email it to them which i did email the required documents and I asked the consultant to block my Makro Card as well. The lady at the Mall Of Africa branch was extremely helpful but she told me that after submitted my documents I need to wait 21 working days for the investigation before the amounts are reversed. That's not acceptable as it is clear that proper authorisation protocol was not followed when the purchases were made **********ly!!! Please get back to me ASAP on this as I do need to use my account and can not be held responsible for R4870.00 purchases which I never made. How do some1 make purchase with my card i never lost an ID, Card or Drivers licence...*Frustrated Client***
