I watched a tv programmee about dodgey traders try to scam you of cash.
They had a PRO locksmith go round to a house and say if he could pick lock it. He said yes easy probably only 1 minutes work.
So they called in the dodgey locksmith and he said there was noway he could lock pick that, so he got his drill out and just drilled through the lock.
Now the customer has no lock on his house but also he had to pay the locksmith twice as much. They then also need to buy and fit a new lock.
They lost out of £100s
