My Makro credit card **********ly used by someone else

I visited Makro in Amanzimtoti today. My total bill added up to around R3000. I attempted to use my Makro credit card but it was declined 3 times I guess due to low credit. I then paid with my FNB card and left with my purchase. I later on received an email from Makro at 22h30 enclosing a receipt for items which I did not purchase. I am not sure how the teller kept my credit details. I only had R298 credit available but the items which this person bought using my credit card amounted to over R600.

I am extremely angry to have this happen to me. My card has been **********ly used by someone else and there is no way I am going to pay for any of that stuff that was bought. Please reverse this unauthorized payment off of my account.
