Chainsaws

bought a brand new mcculloch cs380 a year ago. It's been in storage for a year. took it out this year and found a load of things wrong with it. The break did not work,the blade got hot,even tho' its well lubricated, and the blade went blunt after a few cuts,and the clutch bearings are shakey. the warranty has expired and I'm lucky if I had 8 hours cutting out of it. Took it back to the shop who rang mcculloch(according to him) and they are not interested in my saw. My friend the tree surgeon is convinced I was sold a poor Mcculloch chainsaw. I'm GUTTED. I feel I have been fleesed. I was told to stay clear of that brand and now I pay the price. ADVISE ME PLEASE.
