Called today at 11:-00 AM 3-Feb-13, no answer back but could hear breathing like someone overweight and struggling a bit. Scam of some kind -probably pissed because I always say no to robo calls and polls - just way too many these days and too many scams.

I've been having calls from this number as of September 2012. Not impressed.

Called the number back within 5 minutes and received an answering machine claiming that the number is no longer in service. What bull****. Don't pick up. SCAMMERS. 07Sept2012 @ 7PM.

Rang once. Phoned again, answered, no answer.

Keeps calling but hangs up after 2 rings!!! What's up with that?

The caller asks me to press 1 for agreeing to his question or 2  vice versa. I just hang up.

I do not give to the SPCA and I am getting this number on my phone .  Did not answer it.

You are correct. If you call them, it is a message. They will ask if you wish to remove your phone number. You just have to enter you number at that time and (hopefully) will receive no more fundraising calls.
