Fed up with the service.

We've put a claim in for our tv that got damaged. We were promised to get a tv of same quality and features as the previous one. We received the tv via courier that didnt phone before arriving as requested by us as we were still working. We set up the tv it made weird blocks on the screen and the quality wasn't great. The next day the guy that was suppose to fetch the broken tv phoned me said he was on his way. I was suprised and asked where to? He said to frtch the damaged tv. I then we arent home and will only be home after 4 as we are still at work and need to make arrangements. So he said he will come over the weekend which we couldnt as we were in Pretoria. He just said he will report it to the insurance and I havent heard of him since. Few days later the insurance phoned asking about the service of the claim. I said we arent happy because the quality of the tv and some features arent working. Also mentioned the damaged tv wasnt picked up yet and I was promised feedback still hasnt happened. Over this past weekend the tv started loosing sound but picture keeps on playing. If the tv stays off for long periods it looses power and we have to unplug and plug it in then it works again until the sounds goes. We phoned them today to inform them about the situation. We were once again promised a call back which hasnt happened. I am quite fed up with the level of service. If they cant provide a decent service then I wont be paying anymore. If you want me to move to someone else I will do it.
