Another number that calls all the time but never leaves a message guess it can't be too important

Called back. Recording asks you to wait for a rep and after a few seconds say 'Global Receivable Solutions. Calls a never used land line periodically. Don't have outstanding debt.

Most likely this group.  Looks like a fly-by-night institution.  I'd Ignore and block the calls.
