Unsatisfactory and very dissapointing service DSTV

I contacted DSTV asking them I need a router to ****ect, the place where I am they don't have dish. An agent by the name of lindiwe offered me a monthly router package of 549 a month. They came to deliver the router, they never even come in to connect you and see if it work, to send someone like that, NO! Then I get home after work, I call them to ask how to connect, another agent nini tells me I need to rica and what what, am like how am I suppose to know that when DSTV doesnt tell you and follow up and make u are actually up and running. Then she rica's me, thats what she said. After she asks me if am using a smart TV. I said no. The a big, huge problem starts. Telling the router will work only on a smart TV, I asked why dudnt that person who sold me this thing ask me that in the first place, DSTV agents just rush to close a sale and a debit order, no proper questions to ask first, they just assume everyone is lookiing or using the same thing, so they can close a deal. So I asked now that am stuck with a router I can't connect on my tv , whats the other opting, agent says your phone. We tried the phone it doesnt connect. They log a call, a day later no one calls you. You chat to them again, give them the ref nr the previous agent gave me, Nini, they stil asking me to start from the beggining what my query is, this cynthia agent i chat to now. Told her I won't keep repeating myself for nonsense. Firstly they sold me a router without asking if I use a smart TV ot not, just assumed I have a smart tv. Month end they will be coming to debit 549 of nothing I used. I need this thing sorted out now now now, or this deal cancelled immediately!!!!! I will go connect somewhere else. . . ASAP!!!
