Pathetic service and de*****ing clients

Dstv is *****ing from us apparently our decoder is not working it was disconnected and they are claiming we are paying for 2 decoders in our home yet we have been using 1 same decoder for the past 7 years and have never added a second decoder to our account nor added extra view. Our decoder is off and we just paid full amount for it and we are not getting any help from the customer service rather they are giving us ridiculous stories. This is total ***** from multichoice.
