Poor customer service

I have been getting unknown discounts on my dstv for two months March and April. On the 1st I went to pay after being disconnected.When I got home there was no reconnection and made an enquiry via Facebook and I was told I am owing because of the error their Finance office was doing , before they can reconnect us. Multichoice , so now I need to pay for their errors? I am currently unemployed and been paying every amount they ask for, ********* and professional.All I am asking for is the reconnection and they sort out their Finance office no me a customer for 10 years.Not the apologizing messages,that wont reconnect me.
