They called and asked for me knowing my name somehow and then hung up.

this is a fraud call. the person identified himself as from bell mobility. i am a client of bell but was without a contract since few months ago and was actually looking for one. the guy asked for sin # and credit card # with a cell phone plan that seemed too good to be true. i took all info - agent name, id etc and interrupted the call and asked to call later and then verified with bell customer service and was told no employee/ agent with the name and id exist. further they cannot even remotely match the proposed plan. they do not ask confidential details on phone as this guy did. further they advised me not to disclose information.  
please be aware regarding this attempt to extract information for identity theft

The person called me and said he is calling from some hydro company and but when i said not interested start swearing
