Dstv not assisting there clients

I am very disappointed in the service I received since 21st December. I phoned on the 21st to report that I have no communication from my primary decoder due to my secondary decoder gives the error message. A month ago an credited installer that where send by Dstv installed the primary decoder and month later the installation gives problems. On the 21st December the consultant could not clear the error and said she will phone me back after an hour she never did. According to another consultant I spoken tp today she phoned on 24th December but the call did not go through, why wait three days to confirm it my decoder is working???? I phoned three times before 12 and till now no one came back to me because Dstv must send a installer to come and check the cabling. My decoder is still not working, tommorrow I will phone an local installer because the one Dstv used is 450km away from where I live and Dstv will credit me. I gave them enough time today. Dstv can take the subscription very fast but now I must wait and struggle. PATHETIC SERVICE!!!!!!!!
