I had signed up for an appointment 11/2. Got a reminder voice message with the same 650 632-0728 call back. Tried twice..no reply yet. No identifier on their answering system either so was questioning if I got the number right until I saw all your inputs. Will be interesting when they show up tomorrow and I'm not here.
They did show up 11/2 not out of the SF office but out of Santa Clara. The two young guys apologized stating no one answers the 800 number on the weekends. The gave me a card: Rug Steamer, Professional Carpet & Upholstery, (888) 298-7279. Hand wrote another number on back (415) 632-0728. May help others.
Careful, these people don't seem to be real professionals, probably illegals. They will not show ids and the cards don't match the name of the calling company.
