Shipton's Heating & Cooling Ltd

We purchased a service plan last fall that included maintenance on our furnace and air conditioner. Prior to turning on the air conditioner a couple of weeks ago, we had Shiptons service technician out to fulfill their commitment with the air conditioner. The service technician spent a good hour or so preparing and cleaning the unit. He advised that the unit was good to go but we would need a new capacitor as he felt there was not enough power to the unit. We agreed and had it replaced a couple of days later by a different technician. After replacing the capacitor the technician told us that all is good and we could start using the air conditioner. A couple of weeks ago when the weather was at its hottest, we turned the air conditioner on to find that no cold air was circulating.
We immediately called Shiptons and they sent the same technician out to troubleshoot. This time he took all of about 5 minutes to determine that the compressor was dead and we needed a new air conditioner. As most customer do, we got several quotes immediately and had the air conditioner replaced within 2 days. Installed and once turned on the new AC was having the same problem. The first thing the technician did was he went to the hydro panel box in the basement and noticed that the AC was running on 110V and he changed it over to 220V. He fixed the issue in less than 30 seconds. Long story short, the technician told us that we did not need a new AC and was wondering why Shiptons technician didn't troubleshoot.
I proceeded to call Shiptons and left a VM to discuss a refund of at least the capacitor with no call back. Called them back last Monday and spoke to ..... after explaining to her the above story, she said that she would have someone call me the next day! It is now June 4/16, still no call or reimbursement!!! This tells me that they know they were wrong and now are trying to cover up!! Really terrible customer service.
