If you're that frustrated go and buy a $5.00 pot of woodfiller and fill the holes yourself, then send them the receipt for the woodfiller and have them pay for it. It's not a hard thing to do, at least then you can get on with painting right? When we had doors installed by Home Depot (long long long ago as we do it ourselves now) they never once filled the holes, so we had to do it ourselves and its about 5 minutes out of your day.
We live in an 1870's farmhouse that needs renovations in EVERY room, one bathroom needs completely gutting top to bottom and walls moved, plumbing moved, etc. the other needs a shower taken out, and new toilet and sink, painting, etc. We have TONS of tiling to do, flooring, carpet tile in our living room (we have dogs, carpet tile from home depot the nice stuff is really great), painting galore, ceiling in the living room needs new tongue and groove to match the kitchen, bedrooms all need the plywood pulled up and the spruce floorboards underneath to be sanded, painted, and varathaned, the cedar siding on the porch still needs to be painted, the porch lights need installing still (two hanging lights on conduit because there isn't a drop ceiling), plus.... 13 light fixtures that still need installing, a brand new front window because we have a badly installed bay window that needs to be removed and replaced with a smaller period appropriate window, brickwork needs doing around that, plus the old door next to it needs replacing with another of the same windows, more brickwork... we also need to re-point our house.
Most of this aside from the windows, brickwork, and re-pointing is being done by us. Happy DIY-ers, we just moved in 2 months ago after finishing the project of our Backsplit.
Anything is possible
