They call here for 'Mrs Peterson', thinking that my boyfriend and I are married, and I'm using his last name.
When I tell them he's not around they say 'I'll call back later'. Usually I get "A local charity" but they won't tell me which one, but today I got "Shelley" and she hung up almost before she could finish her name.
It's a Regina number, and I'm pretty sure it's a scam.

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.

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