Dstv bad service

On behalf of my dad

My dad is on price lock on dstv for less than a year

For the past couple months multichoice have been cutting his account saying that there is funds outstanding

However when he calls dstv they see they have made a mistake in there calculations and say the matter has been rectified..... To this day every other week the dstv has been cutoff and when you call the call center you sit on the 0hone for 20 mins and then they say it's rectified and do the same thing over a over again

This is absolute disgraceful service to receive from multichoice

I then called the call center today again and they cut me off after 20 mins and then when I recall there systems are slow and the agents are busy having a party in the background

What kind of establishment is this that they have zero customer service and cannot calculate properly

Totally disgusted with the service I am receiving or should I say the service that I ain't!!!!!
