Sometimes some over-the-phone scammers will use tools to get their phone number to appear as another one than it actually is. I often got some of those free hotel room scams call me with a 613-662 number even though those are actual mobile phone numbers. Unfortunately, there is not much you can do about it.

It sounds like a scam attempt for me. One of my friend has similar experience with illegal phone call. Luckily, she didn't fall for their trick since I kept warning her to stay alert when picked up phone call from unidentified number after I read many complaints posted at https://www.callercenter.com. If ever someone call you and start asking for you personal information or try to make you spend some money, it is likely a scamming attempt. Keep yourself updated and don't forget to also share the information with your family and friends.
