Bad Service received

My father had purchased a Openview HD decoder in July last year. From the time he had it installed,he been experiencing problem with signal. He then contact a approved OVHD technician to see what is the problem, the technician aligned the satellite but we still had a signal problem. So we called him again and he replaced the LNB cable, it worked but still loses sign from time to time or doesn't work for a few days. We had paid for all these changes and when we call the technician to check what the problem was, he tells us that there is a tree in the way off the signal. After we paid for all the change just to get it work. Now we have to pay to get the satellite moved. So we moved the satellite, please understand that my father is a pensioner and didn't have enough money for this. We used a different technician this time and after moving the satellite, we still have the same problem. He had tested the LNB cable and he said the decoder is faulty. I purchased it from Game and I contacted them. They have confirmed that the unit has a 1 year warranty which means I can't get it replaced or fixed. If first technician check the decoder and told us that it could be the problem I would have returned the unit. Now I am forced to buy another unit after spending so much money from following the advice from approved OVHD technician. The Openview HD was supposed to be saving us money then costing us money just to get it to work. All we wanted is enjoy good quality TV at a affordable price.I feel you brand is doing that but I think we were dealt a raw deal here and would like some help in this situation. I have emailed the customer care two weeks ago and response as yet.
