NUDEBT - TV LICENCE

I have been a paying customer every year since I bought my TV. This year I did not get my notice to pay my licence and when ****orker paid her licence I remembered that I also had to pay and then paid my Licence on the 23rd of August 2024. The amount for R265.00 which was what the yearly fee is. For the last month. I have been harrassed by Nudebt with calls and sms's constantly to pay R185.50 which according to them is interest from March to August 2024. I would understand if it was a licence of more than R1,000.00 with the interest but to let me pay almost the same amount of the licence is absolutely ridiculous. After sending numerous emails and also telling them to stop bothering me and start calling people that do not pay their licence they have the audacity to tell me this is my account and they will follow up with me and not people that do not pay. STOP BOTHERING A PAYING CUSTOMER. I will not pay the R185.50 because there is no invoice with interest showing me that I have to pay.
