They've called 2 or 3 times today.  I say hello, and then they immediately hang up.  Probably trying to collect active numbers for telemarketers or something.

Caller Id said nothing I didn't call back.

347-7415 calls 2/3 times per day.  Hangs up after I answer. Today a lady was at the other end.  I told her to strike our number off her sheet.  She said this was the first time she had called.  She said they were a new charity but all charities in Regina use the same phone number???  I told her this may be the first time she has called but many have called from her number and apartment.  She got very nervous that I knew she was calling from an apartment.  Lucky guess on my part.  Again, I asked her to remove our number.  She told me to quit yelling at her and hung up.  News to me that I was yelling.  I dialed *57.

they keep calling me too.. where is that number from

this is who is calling you.  don't ask me why.
