DSTV Account's Department is beyond PATHETIC!!!!!!!!!

I had my DSTV installed on 04 June 2018 and made my 1st payment of R728.10 on the 5th of June 2018. I made the payment using my FNB internet banking and by mistake selected Box Office, not having a Box Office Account. Since then I have been trying to get the account's department to transfer the money and allocate payment to my account. I have send numerous proof of payments to various people within the company. I have contacted the the call centres countless times. I have been to the Newton Park branch in Port Elizabeth with all the documents stamped and verified by FNB. Every time they disconnect my service and every time I have to phone them with having to explain and send emails. I always pay them well before the required date stipulated. This matter has been very stress full not to mention embarrassing. I don't get any feedback. They still haven't fixed the problem. I am not happy with their customer service. I pay the Premium fees but receive the worst service. I really don't know who else to contact.
