Money making scheme!

What a **** of company! I bought an explorer 2 months ago and it has been playing along with my extraview decoder for the past two months with no significant issues. The only thing I had been battling with is pvr. I could not pause nor rewind but that didn't really bother me. Yesterday, I thought I should call them to get that sorted and immediately while they were sorting it out my extraview decoder stopped playing completely. I spent more than 20 minutes on the phone yesterday with Karyn who promised to escalate my matter to the supervisor. Nothing happened, 24 hours later I call again only to spend more than 30 minutes on the call. That's more than R100 airtime for nothing! They then told me to call an installer to help me when THEY ruined it. An installer charges R380 for the service which I am NOT prepared to pay! I WANT THEM TO PUT IT BACK THE WAY IT WAS. I WON'T SPEND R500 FOR THEIR INCOMPETENCE! If this doesn't happen I'll completely forget about them and stick to Netflix because this is pathetic.
