Horrible service

Customer service from dstv has been very disappointing. I have 2 decoders with them and have called in numerous times to disconnect one of the decoders. I did it on self service and they still charged me for the decoder after that they disconnected my services. When i called in the 1 st Lady said she will escalate the matter but clearly she did not cos after that i was disconnected even after i had fully paid for the decoder im using. I called in 2 days later explained the situation to another lady she said she will listen to the call recording and she reconnected me. Today i wake up and im disconnected again!! I called in 3 times and spoke to 3 different ladies they all gave me 3 different reasons and 3 different amounts to pay. Now my question is Why must i pay for a decoder that im not using after paying R509 for my package and after the other decoder has been disconnected. Why am I getting charged 2 times reconnection fees for the same month.??? What is self service there for if your consultants keep telling me that i should have called after disconnecting my decoder??
