DSTV MultiCHoice - poor service

28th October I called DSTV to change from Premium to Compact. It's now the 10th September, and DSTV Compact is still not working on DSTV Now! I phone almost every day, and the call takes at least half an hour resulting in nothing new! My account is fully paid, but the DSTV still says I haven't paid. I've emailed Proof of Payment many times. Called yesterday and was told the account hadn't been downgraded! Simple if this is not resolved I'm blacklisting DSTV off my account! I watch NetFlix all the time anyway!
