Mr. Thomas,
We sincerely apologize for the delay in servicing your vehicle.
Under most circumstances chip repairs only take 20-30 minutes. Regrettably, the day that you visited the shop we were tremendously busy and that required one of our technicians to work on both your vehicle, as well as another customer's vehicle at the same time to try to minimize the delay for both parties.
The process itself did not take any longer, our technician just wasn't focused on your job exclusively.
Once again, I am very sorry for the delay, and we intend to adjust our time estimates to cover any variables that may occur.
Thank you for your business!
