Dstv streaming error

Frustrated and deeply annoyed by a big company that eagerly take your money but give no service. Bought a new streaming package yesterday, can only watch 2 minutes then the tv turns blank and say there is a streaming error. Talk to multiple of the live chat people one is less helpful than the previous one. Switched my tv off more than 10 times now, logged in and out of account multiple times. There is only one device on the account so the streaming problem is definitely at DSTV. I want service or i want my money back!!!
