Caliber Drywall

"This homeowner was given a separate quote for painting of the repairs that were done. They elected to not have the painting done because they decided they would paint it themselves. It wasnt until weeks later that she called and said they would like us to do the painting after all. After scheduling the paint job it wasn’t until days later that the homeowner called screaming and yelling at me because she could see some white showing through in one area and would like us to repaint that one wall. I agreed to come back and repaint it myself. She then apologized for being angry at me and said that they were going through some family problems. This is how she was dealing with it by yelling at me. I asked her to go ahead and provide the correct paint because they provided the wrong paint to begin with and let me know when she would have this done. She calls me back a week later and said she was ready, but I happen to be out of town and I promised her I would do it myself when I got back because our schedule was full already. She decided to paint the 2 areas in question herself and then calls me to demand a refund of $200. I told her that as a contractor, I have the right to come back and make any repairs or corrections on the job. She apparently did not understand this law. I offered to refund $50 of the original $550 that was charged for this total job because it was only going to take me an hour to make this easy fix. She obviously was looking for almost half of the total cost of the paint job in a refund. She refused my offer. By the way, if they were in such a rush to have this done, why did they wait weeks after the original drywall work was finished to call me and schedule the painting??"
