distasteful service and customer handling by TFG

I have experienced the worst service at the hands of Foschini which is part of the TFG. After over 15 years of being a loyal customer whose account has constantly been in good standing, Foschini has put my account in arrears because they alleged the cannot trace a payment I made of R1640 on 5 January 2023 in-store at their Waterfall Mall branch in Rustenburg. I used my bank card to swipe for the payment and despite having submitted an in-store receipt and bank statement which confirm that the transaction was made, I am still being harassed by their deb tors who are demanding payment. Numerous emails have been written to TFG and their customer services department has responded that they cannot track the payment. I have also incurred airtime costs making calls which have yielded no results. Whose fault is it as I carried and fulfilled my responsibility of going in-store and making the payment? This has adverse implications on my credit profile. TFG's handling of this matter has left a bitter taste in my mouth and I warn others to tread carefully.
