Do not deal with this guy

Please be careful when dealing with this guy. Please a cold room with a small compressor. We incurred losses and asked him to change it. His response was I will have a look at it. We paid him and he then was told by my husband to come and take this out and replace it with a proper one. He came toon out the compressor even though he was told to wait for us and he left. He has promised to pay us for over a week and a half but now he does not answer calls on all of his numbers.
