Carrier Mid Atlantic

My husband worked for this company since moving to North Carolina 2 1/2 years ago. He recently gave his notice so that he could pursue his dream of having his own business. The day he gave his notice he was sent home. Recently he called to order parts from them for a job he was working on, and they told him that they would not sell him any parts, but the customer could buy them. Extremely unprofessional and childish way of doing business. All because they are upset that he wanted to fulfill his dream.
