Here's an insight into using locksmiths not from the local area.
I recently attended a job to change a women's lock, while i was their she was telling me she had a locksmith company in several weeks before me.
In the course of the conversation she then preceded to tell me that he had to change the clutch on the door lock.
Well let me tell you now, their is no such thing as a clutch on a door lock, a clutch is in a car, no where else.
Basically what he is doing is adding items to the invoice that can't be checked that the customer has no idea of what they are or what he is telling them.
In other words your bill is going upwards for no reason what so ever other than to pad out his invoice.
These incidents are happening every week to customers who have to trust that the people doing the work are honest.
Most are not and theirs a very good reason for it, most are sub contracted out to national companies on a part payment basis.
In other words the more they charge you the customer the more they get paid after the call centre takes their cut, your basically paying twice for the job.
