Used the wrong product for repairing my pool twice. Charging me both times. Charged for more time on the job than he had. Did not honor bid. Did not back work. Charged for materials and took home for himself, unopened materials I paid him for. He did not read the label on the product he bought to see that it was made for fiberglass and wood only. He said the reason why his cement cracked was my marcite, when he did not use the correct cement for a pool. He cam over to my house unannounced more than once, despite me asking him to not come without speaking to me first. He made a commotion, by himself only, at my home when there unannounced, that I was really afraid the police was going to come. He is dishonest, does not know what he is doing and I fear actually dangerous.
