Accounts Department terrible service!!!

I purchased a new TV on 24/11/2017 and at same time paid renewal of TV Licence. Well before the due date of 31/12/2017 I paid the renewal fees at MAKRO which is stated on their website as one of the pay points after numerous emails to ********** has been sent since January 2018 with proof of payment. No reply received nor has it been corrected. They keep charging interest and penalty for NON PAYMENT and I keep getting SMS`s stating that I have not paid. Emails has been sent and phone calls have been made to the contact center, but nothing has been done. I will not be held responsible for their incompetence in this regard
