Tell your supervisor what's happening so your super will not be taken by surprise if this criminal should reach your super. Disclosure is the best defense. Then consider using a whistle, air horn or screaming smoke alarm to blow his ears off.
Received 2 calls today, one at home & one on the cell. This # also called my work no less than 6-10 times over a 2 week period, ridiculous. Claims his name is "Ryan Johnson". All calls are being reported to the FTC hotline either on line or by calling 877-FTC-HELP (877-382-4357). This is a major SCAM operation out of India. All people called are encouraged to contact the Federal Trade Commission and report this, do not give them money. An online payday loan database was hacked back in December 2011 and many people had their personal information compromised. This is not the first attempted scam via repeated aggressive calls from people with thick foreign accents, I've had to deal with at least 8 others so far since then.
