DSTV IS ******** PEOPLE

I received a call from DSTV a few weeks back, offering me a new decoder, the explora ultra. I am on the compact deal with DSTV and I pay every month without fail. They offered this deal that the decoder come with it's own built in WIFI, streaming apps, pause live tv, recording feature etc. They told me I would get this delivered to my home, and I just have to unplug the old decoder and plug in the new one, and we would start watching. Only to find out that this decoder does not come with built in WIFI, but rather a WIFI connecter for me to connect to my own internet. I was specific in asking the agent who called me, if I did nit have internet at home, would this decoder work or would I need to have WIFI installed to connect it? she said I must not worry the decoder has it's own WIFI. For the past two days, our channels are not playing, I initiated several chats with them to get the issue sorted, only to be told that I need to get an installer to fix an issue, which I need to pay for. If I had accepted the offer based on full information being given to me, I would not have an issue. Now I have to cough out money unexpectedly to get this to work. On top of that I get poor service from them, agents are rude and no soft skills. They just want my money but the service is poor. I want them to compensate me for the cost this has caused me, my time my money my mental health. I suffer from anxiety and this has caused me so much stress that I could not even work yesterday. The AD that they are putting out there of the DSTV Explora Ultra is a lie and **** to get people to be interested only to find out that it's has cost implications that they don't mention to people until you are deep in with it. I feel taken advantage of really.
