My maintenance agreement expired at the end of May, but I did not receive a renewal notice. When I called, the man was just confused about my history and my request. He said I should go online. When I went online, the system would not accept my credit card. I called again to get a paper statement and sent a check for the maintenance agreement. Now, you want to know about your service. There was no service, but I want a receipt and a copy of the maintenance agreement. I WANT A RECEIPT AND A MAINTENANCE AGREEMENT. I am sooooo sorry I purchased my AC system from you.
