Who called from 4162232819

This phone # keeps calling. I have the half of mind to call it back but I'm afraid that it's one of those scams. It is getting really annoying. Has anyone else had this experience? Thanks.

I Called the # back and it says it is a CIBC ph# that is no longer in service and prompts you to call their toll free 1-800# which is valid.

I received call from 416-223-2819 and was given call back number 877-452-8864. I contacted 800-465-2422 (a known CIBC number) which validated the above numbers and the reason for the call in the first place -- to clarify a change in mailing address.

I was contacted by an outside company reviewing my services with cibc.
New all my details but was very repetitive and getting prompted by what sounded like a recording
Kept me 25 mins + talking insurances and interest rates ????
I ended this call
