cannonball pools

"When the concrete was initially poured customer was not satisfied with some areas of concrete. We understood and re poured 5 sections. He also had added an additional $800 worth of concrete to go around the pool, which we had agreed that we would fix the issues and provide the $800 extra concrete which he agreed to pay for. Afterwards we asked if he was OK with the concrete. He said yes and we were still to be paid the $800. He never paid me the $800, and said since we had to re pour the concrete,(which was done within 2 days) he felt he should not have to pay for the additional added. Instead of fighting him over that,I decided to let it go. A year later he decides that there are too many cracks.(concrete will crack eventually.some maybe a little more than others) At no time were we ever unprofessional, not on time, or fail to do what was agreed. Also, the water feature issue is one out of 6 deck jets is splashing a little on the concrete. He told me he could handle that. All it takes is adding another ball valve into the plumbing at the equipment to increase pressure. We also provided and delivered a used set of deck steps at no cost to him so he could use his back door until he could build something later. We always provide excellent customer service to our clients. I have over 50-100 more references available to anyone who wants to call any of my previous customers.Plus we can go visit many jobs to view our work."
