Calls twice a day on my cell around the same time, never leaves a message. I answered once but just got dead silence. This has been happening for a month now

Called on 3/14 at 11:09am; 3/13 at 7:35pm; 3/09 at 4:31pm; 3/06 at 8:44pm.No messages.

Called claiming they were from CIBC and then tried to get private information from me.  I said I didn't feel comfortable giving out any information to a random caller claiming to be my bank and ended the phonecall.  They still call frequently, though, never leaving messages.  They are bastards.

Calls frequently, days and evenings. I have never answered. Caller never leaves a message, just hangs up. Persistent.

received a call from (514) 847-3629 on March 6/09 -

Decided to pick up on latest call. Appears to be a call centre, apparently representing a number of clients based on info above. Male caller, calling on behalf of CIBC credit card services (I do have a CIBC card, so this makes sense), wanting to enroll me in balance protection insurance. Was pleasant and accepted my response when I declined.
