When I do quotes over the phone or face 2 face,I always ask for a mobile number.If I dont hear anything within 2 days I send a standard text message saying.
'Mr Smith,I visited your home on 5/5/10 to give you a quote for a Dralon Sofa cleaning.Please call me at your convenience,and I would be happy to book you in'
I do this with every quote I dont hear from,sometimes its works,sometimes it doesn't.I prefere to send a text because in my opinion it avoids the embarrassing telephone conversation
