bad service

Ii pay my dstv account in the 8th if January 2018 and the was a number that was punched incorrectly and the payment went through to another dstv customer, I immediately contacted dstv call centre and they told me to email the proof of payment so that they can resolve it after a few minutes I was connected but a few day later they disconnect me and was told my last payment was in the 04 of December 2017 and so I called again and was required to email again proof of payment which i did and the same problem happened the whole month each and everytime I call I'm.asked to email till I decided not to do that anymore because they were just fooling around with me. I also reported the query on the Facebook page but nothing has been done instead they handed over my account to Blake associates for collection I explained what happened and I reported the matter again on Facebook that was the 23 of April and they promised to solve it, till now nothing has been done. Today i sent another message on Facebook and they tell me to contact them so i ask them why don't they do it themselves because I don't have airtime to do that. I don't like the way my I'm treated by dstv because thers not even a single month I never paid I made sure of that even if it was passed my due date I paid along with the penalty fees, so why I's it hard for them resolve my query.
