misleading information to get clients

A consultant reached out to sell me a package for R300. Initially, she told me someone would install the decoder for me, but when it arrived, the courier said they only deliver, not install. I called DSTV, and they told me it’s a plug-and-play system, and all I need to do is call them to activate it. When I called DSTV, however, I was told that my dish is incompatible with the new decoder—something no one had mentioned before. I won’t be spending money I didn’t budget for, and the consultant didn’t disclose any of this. Now, I’m being asked to pay R400 because the box was opened while we tried to connect it. It’s frustrating how people can get away with misleading customers like this.
