Pricing and Bad Service

We called and booked them, they then came to our house to set up our Dual DSTV, they gave us a price which was completely different to what they said over the phone, then when we accepted that price, they installed and then they invoiced us for even more, so we had to do an internet transfer.<br> <br> Then after they left our DSTV has been giving us problems, bad connection and giving an error message saying something not setup right.<br> <br> We have called DSTV call centre and they said it has to do with the installation that these people did.<br> <br> Ontop of it since they have been to our house, my Daughters 7\ tablet has just dissappeared.<br> <br> I emailed them 5 days ago and no one has gotten back to us. I think there service is terrible
