I was burned by this before (in SF Bay area). The call center dispatched a guy that took over an hour to finally arrive in his broken-down family van. He came out of his car with a power drill in his hand and asked me where the lock was. The entire time he was smoking. Apparently, he wanted to drill through the lock and replace the whole thing instead of picking the lock like a true locksmith. Luckily there were enough red flags in the whole process to where I promptly told him to get off my property. They still charged me $20 and I ended up paying because I didn't want them to come back and do something to my house. The guy ended up sending my credit card details to "HQ" through a text message.
