NO SERVICE AT ALL!!!! DISGUSTED

My husband owns a Triumph Daytona motorcycle which gave a bit of a problem. We took the motorcycle to Triumph Centurion Lifestyle, as we thought as it is a Triumph dealership / repair shop. What a waste! They had excuses after excuses on what was wrong with the motorcycle. They said some parts are wrong and asked permission to replace it, only to find they never replaced it. We waited for 4 weeks (can be more) and still could they not help us. We then collected the motorcycle ourselves to take to someone else who would be more helpful, when we came there the motorcycle's petrol tank was scratched, some parts were not available to take home and some parts missing, REALLY!!!!!! We confronted them about the tank and they said they will fix and respray the tank, and again when they delivered the tank, it was not resprayed, only the part on the tank that was damaged was patched, the stickers on the tank was removed and not replaced. They collected the tank again and still are we waiting for the tank, going on 4 weeks if not more. When we try to get hold of the managers, they are never available. NO ONE is ever available to assist.
