Undisputed Worst service for year 2018

I have never been disappointed like this in my LIFE. I have 2 decoders under my name. I received an email saying that i can upgrade to dstv compact for R295 valid until march 2019 and i called the call centre then i was advised that i can only upgrade one decoder then i upgrade this decoder ********** 227 yesterday after an hour my other decoder ********** 794 stopped broadcasting is now broadcasting channel 100 only. When i call the call centre they say they can't help me it's a system issue but since yesterday afternoon? What am i paying dstv for then?. My balance on the app is incorrect. I was also told that there are no supervisors available to assist me with my query an an email was sent to back office to assist further and i need to wait 24 - 48 hours for what? for services that i have paid for? No ways i need my services to be up an running immediately and for someone to correct the balance on the app
