Internal ***** and lack of accountability

My cousin's account has been de*****ed assuming this is an inside job. My cousin has never been to the mentioned store and also has never used her account to that max. A card replacement was done at the said shop. She noticed the discrepancy when she received an email stating that her account was over due by over R500.

We have sent an email to the customer department ti Please provide full details of what the purchases were for and also the details of shop assistant who authorized this transaction. And also an explanation what security measures where put in place to authorize such a large amount, while other store confirm such large transactions with head office to confirm the transaction are indeed made by the correct client.

My cousin has since been to a TFG store to enquire and was given a form to be filled and returned. We still await response from Head office and nothing yet. This will negative affect my cousin's credit bureau. Please play your part as your employees are **********.
