I am in the process of a total overhaul in my livingroom. I have completed all of the electric work and the chasing of all of my AV Cables and Audio Cables. I have even drilled and mounted my Panasonic TH-58PZ700 into breeseblock walls with plaster finish. It was all going so well... until the Decorator started his preporation yesterday and instead of making sure that all the bolts were removed from my wall bracket (TV is safe back in its box

) he removed the first 9 without a problem but the remaining anchor bolt must have caused him a problem because he just worked the bolt free making the hole far to big for the anchor bolt in question

.
So what shall I do to make this hole fit to drill again? I have filled it with mortar and am allowing that to go off, then I was thinking of drilling it out and using a Epoxy Resin Injector and filling it with Resin and then drilling it again.
Have other people had the same problem with a drilled hole being to big all advice would be great
