Received several calls from this number but they never left a message on my voicemail.  Today I decided to pick up.  The guy at the other end(spoke really bad English) claimed to be calling from my credit card company offering me a free 5-year accident insurance.  In order to activate this so-called insurance policy, he wanted me to confirm my date of birth.  This stunk to high heaven, I flat out refused to provide him with my DOB.
Where he got my name & number I don't know and how did he know which credit card company I am with?
Watch out people!!!!!

Oh yeah, they are located in Montreal.

They're an insurance company offering service to customers of various credit cards. Because the insurance is offered through the credit card, and the credit card has an ongoing relationship with you, the no not call registry probably won't have any effect on it.Answer and tell them to take you off their lists and make sure that your credit card company knows that you are not interested in telephone solicitations.

They keep calling me several times a day,  usually they call within an hour of the previous call.  It is my cel phone they call,  don't know how they can get my cel number.  I wish they would just f@%k  off.

I too am always getting a call from (514) 227-8723,if our phone company would give everyone free caller block, we could put these scammers out of buisness.

I've received calls from this number several times -- I usually don't pick up if I don't recognize it and they NEVER leave messages on my voice mail. I've looked them up elsewhere and they seem to be some sort of commercial phone spam.
