Caller Id said nothing I didn't call back.

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.

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.

They have limited staff and an autodialer - and so if no staff are available to answer when you pick up, the autodialer hangs up. And calls you later.

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

Same experience here. We have received one call a day for five days. The caller just hangs up. Today we marked the call for trace with Sasktel by hanging up and then picking up the phone and dialing *57. You don't have to sign up for this service if you are a Sasktel customer. After 4 traces (occurences) Sasktel will take care of it if you follow up with a complaint.
