Yes I also was ripped off by Dependable Lock of NY. I recently called a locksmith in my neighborhood (South End Boston). The Company's name was Boston Locksmiths Inc 24/7. I was told it would be $35 for the tech to come out and $15 and up depending on what was done. The guy who came said his name was E-Shay originally of Israel, in his early 20's I believe, with long blond hair which appeared to be dreadlocks.
He took 1 minute to pop my door open using air pressure bags placed in the crease of the door, and told be that would cost me $110 on top of the $39.00. When I told him that was outrageous he told me the quote was $15 and up and that I should have asked him what it would cost before the service.
When I got to work the next day I told my co-workers and someone googled the name of the business and that's when everything came to light. I checked out the location of the original company I called and of course they do not exist.
I hope we can do something about these scam-bag losers.
