Rude, patronising and unhelpful member of staff. While lubricating the main pivot on my recently purchased trek slash, I encountered a loose internal frame spacer that fell into the frame upon removal of the pivot bolt. I consulted trek customer service who were very polite and helpful, they advised the spacer should be under a slight interference fit and not have dropped in, and advised I take the bike into my local store and claim under warranty for rectification. Upon arrival at the store I was met by a disinterested member of staff who was extremely stand-offish and could not have been more unhelpful - He was telling me I shouldn't have worked on the bike, jobs aren't as simple as they seem (referenced a Madone headtube cover replacement job and how the cables/hoses run through it etc. - A very obvious aspect of said job). I queried 3 times how he suggested I could have pre empted this loose spacer and how he would have tackled the task himself - He failed to answer and instead pointed at the logo on my shirt (I was in work uniform, work for an airline) and told me not everyone in my company knows how to do every job. Rude, unnecessary and confrontational. I felt anxious through to the point of collection, to then find comments were left on my workorder regarding 'incorrect maintenance by customer' and 'if unsure to have work c/out by trek dealer'. These seemed completely unneeded to me, the maintenance was not incorrect. Trek HQ acknowledged the issue. I raised this and asked for the comments to be removed, this was agreed but I then had to chase again via phone to get the corrected work order copy sent to me. The phone call I believe was taken by the store manager who was also disinterested in hearing any of what had occurred. I asked a fourth time upon collecting the bike how I should have pre empted the loose spacer and again this was not explained to me. A different member of staff upon collection was much more helpful and engaging. No apology was made at any point. Overall the worst experience I have had in a bike shop (or any shop!), I will never visit the store again and strongly advise anyone to take a wide berth of the place.
