Frustrated customer

I am a victim of customer abuse and financially and harassed by multichoice. I made a payment at Checkers in Durban KZN on the 7th of September 2018 10: 20 am. Ever since then my relationship with Multichoice became sour. I am being treated like a bad player as every 5 days they disconnect my dstv I phone them with my airtime and ask for reconnection and tell them over and over again that I sent a proof of payment for September month, they also agree that they can see the attachment yet, I am still feeling the pain of receiving disconnection messages. Always telling me I am over due yet I am not. Even now my dstv is off. I used round about R1000 airtime when I estimate from September till to date with no help and No hope of getting any help. If anyone can help me I will really appreciate. I am tired and feel violation of customer right and abuse. Also losing a lot of money for the calls I make from September till to date. I do not even know where to claim it. Even made things worse the last call I made speaking with Wandile multichoice consultant had no respect, rude and ended up not helping me. To mention few consultants I have spoken to. Mphumelelo Ngwenya , Khulekani a team leader who never got back to me. Harber from risk department in Jorbag also promised me to follow us the matter. Nothing is happening. I am fed up and really need help and leave Multichoice horrible customer service and abuse. My dstv card number ********** 0451.
