BAD SERVICE, INCORRECT BILLING AND ILLITERATE CONSULTANTS

I upgraded my decoder to and explorer price lock of R499 round about April. When i took this offer i was told that my monthly debit order amount would always be R499 unless if i took something extra on DStv (eg : Showmax, Boxoffice). So last month i was charged R647.35, mind you, i had not rented a movie or subscribed to showmax. So i gave Multichoice a call to get answers, but they couldn't give me answers except the fact that i have 2 subscriptions of showmax, of wich i knew nothing about and they said they can t cancel it on their side, i am the one who has to cancel it. as to how i am going to cancel it, i have no idea because i don't even have the login details for it. so they offered to escalate the matter to showmax with reference number ***0-C1 and this was Snegugu and they told me that i will receive a call with assistance regarding my query. i waited a week passed and no call. i called again and they told me that they are sending a reminder and that the turnaround time for my claim is 2 weeks. i then realized that i will not be getting answers as it seem like the people who were assisting me were not clued up on what was happening. i then reversed my R647.35 and paid R500 wich is the amount that we agreed on upon taking the offer. which caused me R40 extra charged by my bank. Then surprisingly on Tuesday the 22nd Oct , Multichoise deactivated my services as if i did not pay them. I called in to find answers but yet again, nobody could answer me but all they could do was refer me somewhere else. i asked the lady i was talking to to call her supervisor,but because of her bad attitude she instead decided to place me on hold for more than 20 minutes and on top of that she muted the phone for about 10 minutes listening to me venting out my frustration to my daughter, when i finished venting that is when she pressed the hold button and her name is NONDU(please kindly listen to the call). then i called again and found a guy Ayanda M... who was willing to assist but also sounded like he didn't know what he was doing until i got cut off. When i checked the app, i was apparently owing R79 which i still don't know what it was for but still i paid it because my kids needed to watch TV. Today again when i check my app the amount i have to pay is more than R500. CAN SOMEBODY PLEASE TELL ME HOW MUCH I AM SUPPOSED TO PAY ON THIS PRICE LOCK PLAN? CAN SOMEBODY STICK TO THEIR PROMISES. PLEASE
