This is a fraud campaign currently active in Canada using a series of Iristel VOIP numbers. The objective is to obtain your credit card number and drain your account.
If you attempt to "opt out" your number will be confirmed as live and added to a suckers list for repeated future calls.
March 29, 2013 GOOD FRIDAY - 4:20 pm New Brunswick time, just got a call from this number.
Thank goodness I have Call Block on my phone, they will never get through on that number again. Everyone should have Call Block, it is on a cordless phone and no charge for this feature. Best Invention ever.
