Identity being ****** by Milnerton employee

Makro Milnerton keeps using my card number for random customer purchases. First, im in a different province!! Secondly, you keep spamming me with *** and messages as your cashier keep using my card number to make purchases for other customers!!! I demand you investigate what till is using my card number over and over for purchases. This is bordering on identity theft and corporate ***** as you are making purchases under my name and what happens if they try and open accounts under my name now. Stop these unwarranted transactions immediately.
