DStv trying to milk existing customers to compensate for lost customers

So I haven't been paying my DStv account for some time, I check mail messages and see pay R494 for a R399 plan....the penalty is R50 mind you. I pay the amount on the first if the month, by the 8th DStv is disconnected. I make a phone call only to be to told there's R235 outstanding, I can't even get an explanation as to why am I suppose to pay over R700 for a R399 price plan. DSTV SUCKS BIG TIME.
