Lions Locksmith Etobicoke

We called these guys when somebody jammed a piece of metal into our lock on the front door of our business. They quoted our admin person $750 to change the whole lock and proceeded with the work. By the time I learned about the price and stopped it, they charged $100 for service call and the work done prior to stopping. Which would have been reasonable, but I came the following day, removed the cylinder, found new one (for $8.70) but eventually managed to pull that piece of metal from our existing cylinder. I reassembled the lock and it's all working. And I am no locksmith, I'm an IT consultant. Fixed it in less than an hour for zero cost. So, there are two explanations that I see: (a) guy is a bad locksmith, doesn't do repairs, just wants to replace everything or (b) they tried to take advantage of our admin person and charge exuberant price. I'll never call them again.
