Bad service

I recently took my car in for its yearly service at williams hunt William Moffat PORT Elizabeth. The car went in the morning of the service. Midday I received a call from the lady at the front desk for a service report and was told what the cost would be for the service and the replacement of the damaged water pump to the car. I was told to pick up the car the next morning. I then got a call the next morning and was told that the key in the ignition won't turn and was advised to bring the spare key and that also didn't turn the ignition witch was working fine when the car was brought in for the service.William's hunt now want me to pay for the locksmith for the ignition on my car. It's day four and I'm now sitting without a car.That is bad service.
