Poor poor poor customer service

So my screen goes black but my info bar still shows and I had the same problem yesterday. Then I decide to call multichoice to find out what the problem may be. I get through to Phelo who immediately says the problem is with my tv because my services are active. I know my services are active because that’s what the voice option tells you after you type you details in. And I respond no my tv is fine because everything else we use it for works like watching sabc not using the decoder. Then she debates with me and tells me when only there’s an error. Like I have been a customer for a while don’t you think I know what I’m doing?? Secondly, where should I go if I have a problem with my decoder??? Then only after I get upset she asks for my ID number to access my account. So she has been speculating about what the problem is instead of checking and having the nerve to argue with me. As if I’m bored and making up a problem??? No wonder people are cancelling their subscriptions and using streaming. So she logged a technical escalation and gave me a reference similar to my account number ********** 2. Terrible customer service. Shows the appreciation multichoice has for the supporting customers. Technical better get back to me
