Thanks all of you for putting all the information here.
I just received the similar call from Atlanta phone no. 404-382-0475. This guy Rahul Patel is telling me he is calling from some Gujarati Samaj in Atlanta and trying to help people with health problem. He also gave me Atlanta mailing address. But it is possible that they were calling from India actually. He had some local information to pretend they are local. They also try to show that they are authenticate by displaying their knowledge on local events which may have happened in the U.S. in past.
I asked him how he found my home phone no. and he told he got my information from NHS. Some National Health bla bla bla. Then he transferred me to so called, Dr. Harshit Trivedi who is from Manchester UK and running http://theayurvedicnaturecare.com/About.aspx in UK. I tried to search by that Dr.'s name and didn't find any Ayurvedic doctor anywhere. But I did find this website where someone had posted information about these fake calls.
I spoke to him for 15 minutes. I asked him some basic questions on some basic Ayurvedic medicines which are available over the counter in India and he was completely bold over it. He couldn't continue conversation further. If you ask the common questions like where he got his degree and all that he has all that learnt by heart and talks like parrot. But when you ask him question which he has never expected he was completely exposed.
These people are thugs who are targeting people who are not much educated or does not know English and those who are desperate with critical health conditions.
Thanks to all the information available on this page,I was already alerted and ready to catch him red-handed. I am happy that he couldn't even go that far that he can offer me any medication or ask me of any payment.
Whenever you get any such calls please do check on internet immediately and also if you come across such fake calls please do post on such pages so others can be alerted.
Thanks to all and be aware of thieves in-disguise.
