If you have landline phone service, get call-blocking equipment to get more number capacity.
Also block entire area codes as scammers are known to spoof non-existent area codes.
This user has phone service from 01 Communications My home phone numbers are on the
Do Not Call list 01 Communications wont do anything about the misuse
Caller ID says: V90813224000502. Sorry, that doesn't tell me very much. If whoever it is wants to do business (however dishonest), the first thing they should do is properly identify themselves. Perhaps entrepreneurship is not this person's mettle.
