DSTVs poor service

I could not view tv guide for about a month, had a chat with Dstv's facebook consultant, the person told me to reset factory settings, did that.... And now i get an error (the function cannot be performed as the signal strength or signal quality is poor.please ensure that your signal strength or signal strength or signal quality percentages are high enought", i was then informed that i must take it to a dstv agency, drove around and all of them were closed called the call centre but they offered no help, called a dstv installer and informed that i would be charged, i do not expect to be charged for a problem that was caused by Dstv's employee, my Dstv was working before i was "advised" to reset my decoder, 25 December and no television.... With kids in the house nogal!!!! And i pay dstv +- R809 every month
