Who called from 2392247308

I'm in Mayo iIreland and got this call a few minutes ago. 1 ring and I rang back as self employed. Don't answer and don't ring back and report

Just got missed call from 239-224-7104 just now, anyone have any idea how they got our numbers?

It's actually an international number with + or 00 before it. +239 is country code for São Tomé and Príncipe, officially the Democratic Republic of São Tomé and Príncipe, is a Portuguese-speaking island nation in the Gulf of Guinea, off the western equatorial coast of Central Africa.  These are scam calls that will waste your credit
