who is this number

It's a scam, don't give your credit card, master card or any other information to them.

They have been calling my phone for weeks but I never answer a number I dont know! So I looked it up and came here....glad I did :)

I'm so annoyed with this number that keeps calling me. When I answer they hang up, and if i call back it goes straight to voicemail. as well as these numbers
(519) 660-4606
(519) 660-6672

Received a call on business cell phone,indicating they were with mastercard, and due to being a good customer would be receiving a diamond watch, and wanting to sell magazine subscriptions for the price of 3.00/month to cover postage.  Seemed fishy upon learning of this, called the number back, answering machine with a young mans voice stating that this is "PSI" leave name and number... they knew our mailing address etc, might have to alert the authorities The person identified himself as Joe.

Repeatedly calls my cell phone, costing me time and money. When I try to call the number back it goes directly to voicemail.
