This is a fraud campaign currently active in Canada using a series of 604 area code 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.
This phone number is used on Zoosk dating site. Sent to me by a man who calls himself Steven and supposeedly supplies jewellers. Be careful. Don't trùst.
