David Sturza review about company A&B Systems Inc.

I am a disabled man, father of 3, and home owner I got scammed / ripped off by A and B systems Inc.. When A and B systems Inc. started the work my boiler and hot water worked fine. They held themselves to be license plumbers in the town of Islip. I wanted a Gas hot water heater and to add zones to my boiler amongst other things. I am disputing the charges made by my contractor to my visa. He made a total of 3 charges totaling $3,500 of a $4,200 job. He has not finished the job almost 6 months later, what he did do is poor workmanship, installed a hot water heater of lesser quality even though the contract called for a specific water heater, removed all the heating zones from my boiler leaving me with a non-functional new water heater and a boiler that is not working now.
