- SCSteve ChappellSep 1, 20161.0I live in Williamston and feel it is imprtant to support local busiensses whenever possible. GLS H&C is located less then a mile from where I live so I stopped in persoanlly requesting a quote for new Heat & A/C units and was told by the lady at the counter she would have someone call me. Over three weeks later, and no call, I called and agian requested a quote for new Heat & A/C and the lady who answered the phone said she would have someone call me. Over a week later, after no call, I called again and the lady told me John would call me. John called and a meeting date was set...then he cancelled it and another date was set for today, 9/1/16 at 9am. I called John on 9/1/16 at around 7:30am and got his VM and asked if he could come early. At 9:10am, and no John at the house, I called to see if he is coming and he says "Oh yea I had a 9am appointment with you." He did apologize. I told John I was no longer interested in doing business GLS Heating & Cooling.
