Astoria Kitchen and Bath

We just ended a $ 6.5K job with Ronald.
Ronald was very quick to respond to our initial mail and meet us in our new home. Unfortunately, that is where the positivity ends with him. We hired him to build new cabinets, providing granite, for a bathroom and kitchen in an apartment. The problems we experienced with him are below.
With each of these, my wife had to argue with him repeatedly, with him only relenting on threat of non-​payment of the rest of the deposit.
1– He sloppily matched the cabinets we picked to the space near the refrigerator, leaving a big gap and trying to senselessly argue that it looked good enough.
2– When the bottoms of the cabinets were not finished, again, he tried to tell us, the customer, what we wanted and not to worry, rather than having them finished properly and as we, the clients, wanted.
3– He repeatedly blamed our general contractor for errors in installation that clearly resided in his court.
4– When a promised delivery date was missed, he blamed it on the surprise appearance of Columbus Day on the calendar, acting as if it was just randomly thrust upon the City of New York at the last minute without advance warning from sources recognized by everyone, including schoolchildren.
5– Despite this being in the contract, written in his own handwriting, he tried to BS us into believing that he could skimp on our sinks.
6– He forced us to, on our own, chase down his granite supplier and practically beg them to come, only making it happen when we held the remaining balance over his head.
7– He directly lied to us, promising that the granite would be finished to avoid staining with glass rings, etc, and now is refusing to answer our repeated phone calls over a week now that he has the balance.
In short, Ronald has treated us in a dishonest fashion on a number of occasions over the course of our relationship and we would like anyone considering dealing with him to know our experience before going forward with him.
