Refilling Acrylic Tips?

Hi, so I just got acrylic tips on my nails for the first time. Unfortunately, I am a nail biter and stupidly bit part of one off. Also, one of them broke off, but I re-attached it with some at home nail glue from previous fake nails (the type that come in a kit). When I go in for a "refill", are these going to be a problem? Do they have to redo the whole thing and I have to pay again and all that stuff? Pretty much, what do they do at refills? Just extend the nail or can they fully repair too?
