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.

they phone all day long but hang up when you answer.

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

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.

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.
