DStv - Terrible service and call center

I have been using DStv for years and whenever i didn't require service it would be cut and i would pay reconnection fees. All of a sudden i am told that i have a prorated amount i have to pay because i didn't give a month notice to have my services cut. If DStv change their ways of working, why not inform clients because this is totally unacceptable, the worst is when their consultants rudely hang up the call when you ask questions.
