I am appalled at the service

I have been charged multiple fees from multiple for my Explora and they are failing to assist me. When I was sold the Explora I was told that the old decoder would be cancelled, however they started charging me for it again. In November I paid three separate amounts over R500 which I didn't understand.

On the 5th December I paid and yesterday I was disconnected again. I have never skipped a month and when I request to end the contract, I get told that I need to lay for the remaining months. This is ridiculous and a complete *******. They need to sort this out as this was their fault when they didn't cancel a decoder which I have not used for 3 years.
