Terrible experience!

I am having such a terrible experience with Multichoice. My DSTV subscription ALWAYS has issues - I get sudden "Account Inactive" E-16 error codes, unauthorized decoder swap between primary and secondary, I get told that I have not paid when I have and have to send proof of payments to prove that I have never defaulted on my premiums, I get told about cancellation fees unknown to myself, I sometimes get told other stories that are unheard of. I need to call atleast once as week and everytime I do, The agent promises to fix the problem then ends up messing something else and capturing wrong noted on the system - which then confuses the next agent. My only sin was to upgrade to an Ultra decoder for my Extraview. I am really exhausted with their terrible service.
