bab,bad

I bought a Startsat New HD decoder the 4th of march every thing was fine until the 6th of March where the decoder totally didn't show any programs i called the contact center the restored some of the channels but the South African channels were off , so the agent told me she will hand the matter to the technicians the will call me the Saturday , i waited Saturday no one called me so i decided call them they tried to restore channels that was lost but to no success i even talked to the supervisor we could restore channels so i decided to activate my old decoder because there no progress what the supervisor said he will send a technician so i have been waiting from the 7th and today its the 17th ,no one has contacted me , this is a very poor service it shows that you don't care about you client , really i can rather go to DSTV and take your decoder back and refund me
