Multichoice bad service

I have bought a dstv decoder with a one month free compact subscription and the installer called multichoice to activate the voucher the consultant said it was activated. After few days the deactevated my account, then I called stayed in the line for almost 1hr then they told me the discount of one month free was not loaded but they Escalated to the finance departmet and reactivated immedialtly.

This week again they stoped it and I called again they said the voucher is still not loaded called three consultant with no help only my airtume went to waste. I re-explain the situation they now told me they request slip in order for them to load the voucher and reactivate my account. Now the three consultant telling me the don't have the power to reactivate until the voucher is loaded.

so now its not my fault that they did not load the voucher on the when I stalled the dish and they keep on saying it will take 24 hrs and my kids are sitting without Watching TV. We on half a month now yet they keep of deactivating my account now am now my account is still deactivated yet month end ill be expected to pay. I want to return the decoder and get a refund I don't understand why I have to suffer so much by multichoice when I did everything right and consultant telling me different things. Some consultant hang up on me, like i feel helpless.
