Cards are cloned by MRP employees

Yesterday I receive an SMS from MRP Group to confirm if I did a purchase at MRP Fochville and Carletonville at 13:30. I needed to reply with Yes or No. Of which I rep**** immediately No. I then called MRP head office. I was told to go to Police station and complete an affidavit and email them. Of which I did. And sent the affidavit with an email. I called them today and they told me they are going to charge my account with interest of what was ****** on my account and they will journal it once the investigation is concluded. So I want to warn MR Price customers that they must be careful. At first I can only swipe my card at MR Price only. The only way to clone my card is when working at Mr Price. They are the only one who can clone that card. Unlike the bank card were I swipe everywhere. Mr Price is also unfair to calculate my interest on money that was ****** because I have already declared crime, why must I have to be inconvenienced by the crime I did not commit. Yes I understand about doing affidavit but paying interest on clothes ****** under my name is totally unfair and unjustified.
