Joey...
Had a similar encounter awhile back. This person had asked if we were receiving the discount etc and asked to see my bill. I explain to him that I had neither the time nor the desire to go looking for it and that if he wanted to leave some written information that would be fine. He went on and on about this and that and calling me at a later date. Here is the kicker...in order to call me back, he not only requested billing name, address, phone number AND account number but said that I had to sign the form for them to call me...ummmm I Don't think so! After I told him that I was not signing anything he gave me his little speach again about how it was just permission to call me etc....funny, these companies have never needed my permission to call and bother me during dinner etc. Anyway, he wouldn't give up and I ended up having to just shut the door. After reading your post, I am even more glad that I did not sign that form!
I have a standard response now to anyone that comes to my door or calls me on the phone........
"Due to the high occurence of identity theft, I do not conduct personal business via (insert phone or door to door here) unless I initiate contact, have a nice day and remove me from your list."
