Gunsmith whined - Leupold RifleMan Rifle Scope Mount Bases

I bought a new Rem 750 and mounted this on it, then put an inexpensive Colorado 3-9x40 scope on top with the rings that came with it. Things were fine. A week later upgraded to a Leopold 3-9x40 at Gander mtn where their gunsmith mounts scope and bore sights for free. First he whined about the rings, gave him second pair, then he whined that the scope and rings did not line up probably with the mount. I mounted the Barska scope myself, no problem. Now I have to go in and figure out what this "gunsmith" complaint is. If it has any merit, will update this.
