Promised to send a locksmith within a maximum of 2...

Promised to send a locksmith within a maximum of 2 hours having checked that there were 'technicians ' available in the area. Then called me back over half an hour later to say that they were not able to send anybody. We were locked out of our house with two young children. I even turned down another locksmith during this time who was then not able to come as he accepted another job. If they can't do the job that's fine but don't accept the job, take all the credit card details then leave us waiting for half an hour before deciding you can't make it!
