rang three times in the night with only ringing at the other end

Getting calls as well.  Just beeping sounds.

Calls at midnight, with beeping sounds at other end

This is an outgoing fax number at US Plastics in Ohio.   They send out invoices for shipments sent on internet orders.  Very reputable company.  Somebody is probably supplying them with a transposed contact number.

I recently did submit an internet order to US Plastics. Not sure why they would be calling my cell number with a fax tone (?)
