Both the 401-283-7996 and 623-900-7781 numbers are being used by India madarchod moo-fos in Mumbai to sell fake back braces, knee braces, and "medical alert devices". In fact, it is nothing more than an illegal ploy to steal your credit card number. They ask for all your personal information, take your credit card number, and then you receive nothing but have thousands of dollars in unauthorized charges stacked up on your credit card.
For all of these greasy stinky India scammers, I always like to call them back and toy with them for as long as possible, pretending to be an interested and involved caller. That is the best way to retaliate. They do not respond to any request to have your number removed from their database and they do not care if you yell at them or threaten legal action because they are poor idiots hiding in call center sweatshops in India. Some of them may even laugh at you if you threaten them. I have toyed with more than 8 of these idiots by keeping them on the phone for at least one or two hours while I continued to work at my keyboard, clean house, or cook. And two hours later when they finally realize that I am really not going to buy into their fake drugs, fake credit card services, or fake computer virus or IRS threats, I can hear their voices become more filled with fatigue and frustration. LOL!
You can drag out these phone calls and really wear down their patience and energy by faking the voice of a very old person. These scammers especially like to prey on old people because they think their senility makes them easier targets. So I pretend I am very old and hard of hearing, I purposely talk very slowly, and frequently ask them to repeat what they said and to talk louder because "my hearing aid battery needs replacement". LOL!!!
