Unable to fix my account

My payments were all in order till June 2015. Then Multichoice did a system upgrade and from June 2015 I am trying to get hold of someone that can fix the account so that it is not in arrears.<br> I have send through proof of payments for the past 4 months but nothing is happening and the best part is that every 5 to 10 days they disconnect my services and then after an 1 hour on the phone explaining the whole process again they reconnect me. This then will repeat itself in 10 days again.
