Bad customer service again..

Once again I received bad customer service from dstv, I had a problem with my signal for a long time.. as I was only picking up 50% of my channels, and paying my full installment......... Was told to get an installer at my cost, did it.... Upgraded the package and decoder... I got the u5 decoder that only views on one tv,(no cloneing)... Went to multichoice and requested advised, tje lady at the front desk advised me to purxhase a deplexer as this will work...guess what!!! IT DID NOT... return it to zakspeed, called in, and was told I have to get out an installer again, to setup extra view at R85 a month.... Then my service got cut due to prorated charges, as I specifically asked the advisor if this will be added to my month end bill," she reply yes"...( it seems I always have problems with dstv, and I have to jump through hoops to fix the problem, when I am paying for a service.... Perthetic I think, BAD customer service all the time every time)
