Poor service from Price Lock Team

I've upgraded my Price lock with DStv from November 2021 for the duration of another 24 months, of which we agreed that they will debit my account R569 pm for the compact deal, the amount include 3 of my decors insurance, however I've notice that every month that keep on debiting me different amounts, than the agreed monthly amount of price lock, of which i didn't react to it, however for the month of February i called their call centre as my extra view was not playing, upon calling i learned that my price lock deal was removed & they are now charging me normally but for 2 decoders, I told the call centre agent this was not the deal I've signed for & could she please revert my account back to price lock deal & connect my extra view for my other decoder, she did this however after few hours of reconnection my extra view is not playing again, I called the following day & a call centre agent could not even understand what was happening on my account & she could not connect me & escalated my query to Price Lock department, I've been wait more than 72 hours for Price Lock dept. to call me, Ill like price lock team to call me TODAY (23/02/2022) so that we can sort out all this queries, as I'm paying for the entertainment I'm not enjoying, if i don't get a call from Price lock today, I'm going to stop DSTV debit order from my bank once & for all.
