I doubt very much if the lab would respond in a such a petty way.  Best not to attribute such unprofessional approaches to a company that has more work than they can handle for as far as the eye can see.

"I think the time frame was two weeks and that turnaround will not start until they are in full operation around mid May. I would also expect that the present lab would not be in a hurry as they know they are getting no more business from Mcfaulds."
