Dubious contract and bad customer service

On the 29th January 2018, I was offered a contract that gives you a free explora on the premium bouquet at R750 per month. I asked the sales agent if this included all the features of the explora like the recording, catch up, box office and dual view. She said it did and I would not be paying anything more. I was currently on the premium bouquet which means that when the contract starts I would not need to pay any pro rata. On the 25th February 2018, I phoned into Multichoice because I could not access all my channels and I also inquired about the R2112 balance that reflected on my DSTV Now app. The agent told me that he couldn't see the contract on my account and could only see that I have the explora features. He said he will look into and get the amount reversed. On the 27th Feb I phoned in again because I saw that DSTV tried to debit the amount of R2112 from my bank account. I spoke to Raquel and she also told me that she couldn't see the contract being active on my acc. I told her what happened and that I had already received the explora at the beginning of Feb and it was installed. She said she was going to listen to the sales call and let me know the outcome. I didn't receive any response since. I then called in again on the 5th or 6th March and I asked to speak to a Manager, I was referred to Dlamini and he also said that he was going to look into this and get back to me. I have had no contact or response from him since then. I am really very disappointed and frustrated with the lack of customer service and also at Dstv for not upholding their part of this contract. I should only be paying R785 pm as I also agreed to the insurance on the explora which is R35 pm. I would really like Dstv to sort this issue out because I agreed to R785 and not to anything else, currently my balance on my Dstv app shows R1097.81.
