I would take the car back and get them to do it again, as the timing will be wrong.
You paid them to do a job, and they haven't done it properly, it is as simple as that.
You will be loosing performance and fuel economy, and there is a chance that the belt isn't tensioned correctly.
You could always buy a set of locks, then when you have done the job sell them on.. You will loose very little cash doing this.
