Chipping paint
I had a condo remodeled in Maui, Hawaii. The walls were cement mostly with heavy texture and high gloss paint. I had the walls resurfaced, lightly textured, and painted with flat paint. The walls still seem soft in spots, I can press my fingernail in, and the paint chips off VERY easily. It has been a year. The contractor said it is because i should have used a semi-gloss paint..... What was done wrong and how can I fix it?

Welcome to the forums!
Is it just the paint chipping or is some of the mud/texture coming off with it? Is there any moisture in the masonry where the soft spots are? Using flat paint instead of semi-gloss shouldn't make a difference.

The paint chips as well as what is underneath it. It dings very easily. The main walls are cement, with a few framed sheetrock walls. It is a humid environment, Hawaii, often windows are open for air, and AC is used occasionally also.

It sounds like the mud/texture is failing and not the paint. While latex enamels repel moisture better than flat latex, primer and flat latex paint should give the walls enough protection from the humidity.
I assume the walls were resurfaced with joint compound which is water soluble. Are the issues just with the inside portion of the exterior walls? Are those walls sealed on the exterior?

I believe so, with joint compound. It seems the same on all interior walls, the cement ones and sheetrock ones. There are other condos on either side, we all face the ocean. I am not sure if the resurfacing was sealed or not? That was the first thing I wondered. I was trusting it to be done correctly, unfortunately. If the back of a chair bumps the wall, paint and resurfacing come off. It almost seems chaulky in a way....

It's difficult to fix it after the fact 
Basically you'd remove whatever is loose, patch as needed, prime and paint.
Most coatings, including j/c don't adhere well to chalk. What was the condition of the walls prior to the work being done? If they were chalky, the chalk should have either been washed off or coated with certain primer/sealers that will bind up the chalk.

The walls were cement with heavy texture, and a high gloss paint, indestructible.
They were sanded, then retextured, hopefully sealed, and painted with flat paint. That is all I am aware of. The paint is not chipping without being bumped. But, when bumped, it comes right off and, depending what bumps it, dings into the texturing easily.

It sounds like the walls weren't sufficiently sanded preventing the j/c from creating a good bond over the gloss enamel. Since it's not always easy to sand the enamel well enough, a solvent based primer is often used as it will bond to the enamel and the j/c will bond to the primer.

Live with it while it fails or be more aggressive and remove all of the loose stuff you can to get back to the gloss paint, then use a solvent based primer on that and re-do the texture and paint.
