Thank you for speaking with me yesterday. I was wondering whether you've thought of any more questions about our service that I could answer for you?
I appreciate that you are very busy, but if you could reply to me (either by email on firstname.lastname@example.org or by phone on 01262 3417197) it would be much appreciated. If you're too busy, I'll contact you by phone in a couple of days.
Pudsey Info inc.
P.S. Samsang plc has just purchased the same service that you are interested in buying.
