DO NOT TRUST THIS COMPANY! I purchased a Duct Cleaning voucher from Dealfind, and have had two different appointments for Graham Services to come to our house. They have not showed up either time. I am unable to get in touch with them....they NEVER pick up the phone, the one time they actually did...the guy hung up on me! Anyway, they are blaming Dealfind, which I don't believe. Dealfind is offering a full refund. Graham Services is a complete scam....stay away from this company!
