This is NOT a Bell phone number. Bell uses either 1-866-xxx, or your area code + 310-BELL. I wouldn't give out any information on this call, which you should do on a call you didn't make anyway.
ONLY call back numbers that can be verified. We see a lot of 'it's real', 'it's fake' posts on this site. ONLY use numbers from phone book, paper statement, real web site & back of cards.
