Mediocre carrier... I'll use him only if I'm stuck.
Serge tends to "guess" where his trucks "should be" and is often wrong.
ie: "He's delivering now" at 8:00 AM... then your customer calls at 10:00 AM looking for the truck... you call Serge back and he says "I thought he was there but he's going to be delivering in an hour."
Yeesh... if you're not sure... say so... don't guess (or lie) just to get me off the phone.
