********** Purchases on Game Store Card

On Saturday while at home in the south of JHB, I received a SMS that there had been a purchase for R7999 made on my Game store card. I immediately contacted the number provided on the SMS and was advised that there were in fact 2 purchases made at Game in Sandton. I was put on hold as the agent requested to contact the store. When he got back to the line I was told that he spoke to the control room at the branch and the individuals that made the purchases have already left. 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 drive in really terrible weather conditions to get an affidavit from the police station and then to take it to a branch. The lady at the Glen branch was extremely helpful but after she submitted my documents I was told that I need to wait 31 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 over R15000 of purchases which I never made!
