Left my bike here for service and I was told it would be about a week before they looked at it, 3-4 weeks later with me calling every weekend they haven't even looked at the bike and when I finally get frustrated with them they finally want to look at it the next day, this is unacceptable and they kept giving me excuses it's busy meanwhile I could've went somewhere else and they promised me 2-3 days to look at it, then I proceed to ask for a manger and was left on hold for 8 minutes until they hung up the line, I called back for the same employee to tell me the manager isn't in today and he could've said that the first time around without wasting more of my time
