Dstv ultra decoder

I was contacted for a dstv ultra and price lock which sounded good however the sales personell did not disclose everything to me.. First of all I don't have a router running 24/7 in hlmy house but my decoder wouldn't work of my data off it wouldn't allow me to catch up or watch normal TV without data and that shook me because with my previous explora I could do anything and everything without data. I then contacted them to fix the problem and that never happened I called in to cancel the ****** thing as it was not working but the consultant ddnt inform me about the changes that would happen if I canceled the package. Now multichoice decided that it was going to debit R4200 from my account for a decoder that was not working. I called dstv every day as every consultants tells me that they will escalate my issue.. I am so tired of multichoice its not even funny.. People must never take the price lock nonsense. They don't disclose everything to I had to even request recordings of the conversation I was having with the person who sold me the ultra decoder and I'm still waiting..
