CAN SOMEONE ASSIST PLS?!?!?!?! REFUND & PAID UP LETTER!!!!

I am currently at the end of my Debt Review programme. Sadly my distribution agent made an erronous payment to Edcon/Edgars after my account was closed already. Account was written off on 2020-03-24. Payment was wrongfully made on 2020-05-06. From there we have been given the runaround with no success.

Edcon owes me the refund of the payment made in error, as well as a legally acceptable paid-up letter to supply to my Debt Councillor. It has been 3 months without any joy in this regard. Absolutely none. Emails arent answered, or responded to with ****y feedback, requesting documentation over and over and over and over and over again. Yet, no movement. Now all of a sudden, my account doesnt exist. WHAT? You admin issues should not be palmed off onto the customer. I have supp**** proof of transactions over and over and over again.

CAN SOMEONE PLEASE ASSIST?
