I received multiple calls during the day from this number ... the caller has no ID or leaves a message... I suggest don't answer it and block it if you can; certainly don't call it back that only provides your number as being an active number.
Received two calls from 202-221-2213 on 7/13/16. Caller said he was from Microsoft and wanted to install software on my computer to remove an infection. Said their system had been receiving reports from my computer that it was infected. Reported it as a scam to the National Do Not Call Registry https://complaints.donotcall.gov/complaint/complaintcheck.aspx and Federal Trade Commission: https://www.ftccomplaintassistant.gov/
This number calls countless times per day. No message. On one given day it began calling at 8:30 am and called every hour to half hour for eight hours straight! We never answered the call as the number is unknown to us and we can not identify the caller thru various searches. Does anyone know who this number belongs to?
