Poor customer service

4 Call Centre agents had 4 different information on one account, they could clear error as I could only watch one channel. I made 4 calls I made and 3 live chats over 4days to resolve an issue on their system. Poor customer service, on call no 5 on the same day one of their service agents resolved the matter, just to mention this was after the previous agent told me my decoder is faulty I need to call a technician as on their side all was clear and working and theres nothing they can do.
