Lock Surgeon

Called for a quote to fix a few items and was told it was an hourly rate. When the guy arrived I figured since it was such small jobs (prepping a house to sell it) I figured since I had him there for an hour I would get him to do 5 small jobs (3 I could have done myself) - 2 wobbly door knobs (one the guy said he didnt have the parts so mickey moused it), 2 doors that swung shut so needed a hinge adjustment, and 1 track on a pocket door that needed to be leveled over a bit so it didnt rub when opened. This took him 3 hours and he charged me $812!!! I paid half on site (still an overpayment) and spoke to the office that told me their work as comparable to buying a hamburger at Earls instead of McDonalds? She was rude and unprofessional. Said was a per job/per hour which i was not told but only had it verbally said to me and a witness - not in writing. 3 of the 5 items returned to their previous state - both door knobs became wiggly withon days and one door swung shut again. Rita called demanding remainder if payment - I gave them a few reasonable options to come to a resolution and they would have none of it. Wouldnt work anything out and sent the remaining $400 to collections. DO NOT USE THEM!! I had the 3 items they never fixed by another guy for $150!!
