Net Nine has gotten bad and keeps getting worse

Over the past few weeks sub 2 months ive had countless issues with net nine nine, their agents seem clueless in what they are doing 9 times out of 10.

I asked to downgrade from the R700 package to the R500 package this morning, and because i had paid up till the 1st of the Month, they assured me i will be paid up until the 1st of the month, but on the dashboard that is not the case, it says i am paid up until the 29th of the next month, even though i made full payments, infact it says i will be charged an additional R33 ontop of making full payments, i have called over 5 times, either the agent seems clueless or the call gets cut off, their line has been particularly bad this morning, this is not right! I'm losing about 2 days of connectivity even though i made full payments and am being charged extra for no real reason.
