Just got this one on my (Rogers) Cell.
Tried to call back, the call would not go through.
I normally get maybe one spam call per month, but in the last few days there have been a bunch from the USA.
It looks like my name has been put into some caller list; as it happens, I did leave my number at a website last week - but since it was an ISC2 security organization, I figured it was safe.
They phoned my cell (in Alberta, Canada) and so I phoned back on my home phone to tell them not to call again. They said "Ok thank you" and hung up, they didn't even give me a chance to tell them that it's a different number I don't want them calling! I phoned back 6 times to tell them my phone number (they hung up every time). I told the last guy that it's a different number and half way through me telling him the number he hung up!
