GAME STORE CARD USED AT CHECKERS DIAMOND PAVILLION **********ly!!!

I have a GAME store card for several years now, the last time I used it was at Game Eastgate Mall in April 2019, then BOOM 03/06/2019 I receive an sms thanking me for buying at the store R2 272.58, I call their call center Im told the card will be blocked and informed to take an affidavit etc to a game store branch, while im talking a 2nd sms again for another purchase R349.99 , total is R2622.57 used **********ly , I inform the call center agent assisting me about this then he confirms it has been blocked , when I ask where did these purchases occur im told in Kimberly IM AT HOME AT THAT TIME IN JOHANNESBURG WITH MY CARD IN MY HAND, On the 5th i went to JHB Game the lady who was assisting me looked like she did not want to help, eventually she did when she saw I was not there to entertain her ****, I spoke to someone else who confirmed they received the documents. A week later I call i told no one has been allocated to my dispute, someone will contact me which never happened today its 11/07/2019, im told no one has worked on this, it will be escalated, im transferred to this lady at the *****/disputes department I had to repeat my ID number 4 times to her!!! then I get told it will only be finalized next week when I have been waiting for a month, what annoys me the most is that on my credit report It shows I owe R4500+ when I only owe +- R1283 on top of that Im being charged interest. On the statement it shows that the purchases where done at CHECKERS DIAMOND PAVILLION, How can a Game card be used at Checkers? Can someone do their job the game store card is ***, this must be sorted out by close of business tomorrow 12/07/2019 and my credit corrected by 19/07/2019.
