I would look at this as an opportunity for improvement. What you have here is "sales" making a "promise" to get the business. They figure at the end of the day 2 or 4 hours won't make a real difference and they will be able to smooth any unhappy customer over. Your own internal measurements are just those -- internal.
See your sales people want 2 hours or less, cause the customer is pushing them (they'll say anything to make the sale). Your support people want 4 hrs. or more, cause they already have enough work (and they don't want to look "bad").
It is no different is our business and lead time. Customers are always pushing for shorter lead times. At some point you just can't do it. So you either tell them the truth -- here is what we'll do and do it. Or you tell them what they want to hear and deal with any consequences later. It is a balancing act.
You will need to look at your process and determine what is reasonable under the circumstances and go from there. Good luck.
