Faulty Decoder

I moved to the new price lock contract for DSTV. They said I must pay an adhoc payment and then they will send the decoder withing 2 weeks. Almost a month and a few phone calls later they delivered a decoder. I phone their accredited installer to come and install, an installer which more than once said they would phone back. They never do so I had to phone them more than once. They came and installed the decoder. The day after they installed I had a look and the box office wasn't working. I then phoned the call center again. They said I must plug it out, restart and then after all this said I must wait for 48 hours. After 48 hours it was still not working, so I had to phone again and they said I must phone the installer to come and check it out. After 2 phone calls to the installer they came out again. Had a quick look and said there is a problem and I had to take it to their office. I phoned the call center, telling them I'm not happy about it. They made it clear to me it is not their problem and I have to sort it out. So after a lot of money spend on phone calls, I'm still sitting with a faulty decoder that is now my problem and which they would not assist me with. <br>
