Dstv makes me angry

We have taken a dstv price lock contract each and every monht we have to fight for our accnt to be on the right prices we even ask last month march to downgrade we payd over R1500 to get it done then our accnt show R0.00 that we thought oky from now on we gone stop stresing about fights for our account 2weeks back it show R1888.00 we were like what the hell and ask a live chat agent and they say no dont worry it will come down becus of system failures . Today i check again its still R1888.00 and went to live chat and agend say we own dstv R700 and something i ask agent how can that be becus i payd account up to R0.00 and they say i must pay the R1888.00 now its more expensive as before ....
