Poor Service & Missing Payment

am beyond disgusted. I made a payment of R1200 on the 28 January 2023, I have a receipt confirming my payment. My payment is been missing then even after forwarding multiple proof of payment to the accounts department. I phone them atleast once a week to check if the payment is allocated but to my surprise they always ask me to forward proof. Yesterday I phoned again to check the status of my query and also to check the reason behind multiple interest, call out fees and collections fees that are charged but the last who assisted me told me that payments are handled by an outsourced company therefore there is nothing she can do to help me. I then asked why they haven't escalated to the relevant department and she just pushed the call to the other department. I am frustrated because interest is charged on a daily for the mistake they are failing to correct. Consultants are extremely rude and inhumane they told me that I can log a case with my lawyers if I wish to do so, but they can see how frustrated i am due to lack of customer support.

The interest charged is totally ******** and unjust, I receive threats from TFG stating that my credit record will be affected. Even after I explained m issue I still receive collection calls. I went from Markham, Foschini stores but still no one bothered to give me feedback. I emailed my bank statement together with the receipt but st
