FAULTY NEW DECODER WITH ERROR CODE E30 FOR OVER 1 MONTH WOTH NO HELP FROM MULTI CHOICE

I have been a DSTV Customer for a very long time now, My decoder stopped working over a month ago and I called DTSV more than 5 times and spending over an hour for each call using my airtime. When they could not assist with getting my decoder working I was advised that I should take it to the nearest Multichoice office which I did over 7 times and still my decoder did not work. I was then advised to claim for the new decoder of which I did and it was delivered by installer who brought a faulty one with ERROR CODE E30. They then took it back and brought another claiming that this one was fixed and it works. Long story short the second decoder does not work up until today. I called numerous time, spending long hours on calls with DSTV Call Centre and Insurance Company and the CODE E30 could not be removed. I was advised to take it back to the Multi choice offices who also could not help and advised that I call the Insurance company to reclaim for another one, of which I called several times with long hours using my AIRTIME and up today I have not heard back from the Insurance Company and it's been OVER 1 MONTH now I am still sitting at home with a BROKEN DECODER STILL SHOWING ERROR CODE E 30. Insurance Company still taking my payments. This is ridiculous!!!
