333-307-6650

The same person calls from 614-906-7707. Calls nonstop asking for employee information

This call came through as 923333076650.  Country code 92 is from Pakistan.  International Business Times and AirTel both warn against calls from +92 out of Pakistan...
According to experts, +92 is the country code of Pakistan, and miscreants use this code and call up unsuspecting cellphone users to siphon off money or lure them into a scam. Despite alerts from police and cyber security experts, cyber criminals from Pakistan and elsewhere continue to waylay mobile phone users and make easy money.  
These fools keep calling my company asking for people who do not work here.  Very suspicious!  Beware!

AirTel says - We would like to issue a general advisory to caution Indian telecom customers who are being arbitrarily targeted by calls fraudulently claiming the recipient customer as being a Prize/Lottery Winner.
In these types of phone frauds, the customer returns a missed call to a +92 or +375 country code and inadvertently reaches a fraudster pretending to be representative of airtel or another Indian mobile operator and informs the customer of having won some lottery/prize money. The fraudster then attempts to trick the customer into divulging sensitive personal information and to pay a commission to receive the winnings. Such commission is usually asked to be paid via an international DTH operator’s recharge vouchers.
To protect all our mobile subscribers from such malicious activities which may result in substantial increase in your phone bill, airtel would like to advise the following:
» Do not respond to any unexpected calls from a number with the +92 or +375 country code. Click here for more details
» Do not respond to any suspicious missed calls from unknown numbers. In case of such suspicious calls, please report the same to us immediately at airtelpresence@in.airtel.com.
» Do not get lured into any financial transactions or divulge any personal information like IMEI, Bank Account number and other information to callers offering prize money or lottery winnings. Also do not respond to any instructions to dial an international number to get the prize money.
» This luring may also be done through SMS messages offering prize money and seeking personal details on a specified email ID. Please do not respond to these.
» Do not respond to any SMS/Email from unknown sources prompting you to call on a number or go to a site offering free download of content/movie clips/pictures.

This same caller as above, also calls from 011923333076650 or 923333076650, 815-695-7849 and 614-906-7707.  He has called about 6 times in the past 2 days, and says his name is Dr. Neil Robertson from New York Presbyterian Hospital.  He's definitely a foreigner and there is NO way his name is Neil Robertson and he's certainly NOT a doctor!  He's rude and pushy and I keep hanging up on him.  He has a list of names and keeps calling and calling.  Beware!  This idiot is a liar and up to no good!
