Repeated messages left breathing and mumbling on my office line

This number has called on and off for the last 4 weeks, a woman asks for the owner of the company by name, finally pushed to get information as to why she was calling said it was to renew his Priority Card.  Have you ever heard of a hotel chain actually calling to renew a free card.  Tried to call number back and it rings and rings.

Tried to get info on credit cards and debt consolidation.  Opened report with local police.

Started receiving calls 4 days ago.  Has called twice today already.  I haven't answered b/c I didn't recognize the caller id.  They have not left any vm's.
Annoying.....

called my house in Edmonton.
Did not leave any voice mails. Caller Id says HMC International.

They have called also, I have no idea who they are...

Same here they have called me 10 times over the past few weeks. I never answer unknown calls.

these ridiculous unwanted callings need to STOP.

Yes, same thing here.  They call and hangup...no message.  Maybe it's Santa?

I've received at least two phone calls a day sporadically from this number in the past month.  The caller does not leave a message

They've called 6 times in the past three days....
