Multichoice company is a crock !!!

Good day. I have a Compact decoder with 2 extra views and a premium decoder. I have contacted multichoice to block the compact decoder as it has not been in use for the past few months, however they have been charging me for the subscription that was not in use for the past few months and I was not aware until now that my current subscription is giving me problems. Now for them to re connect my premium subscription they are charging me double the monthly installment. I am very furious as they are refusing to re connect me even if the fault is from their side. The call centre put me on hold till I was cut off due to me wanting to fix the problem. I am a farm resident and can't make it to the nearest store. What do I do?
