is this a true Loan company

If someone is cold calling and offering a loan, do not do business with them.  It probably is a scam.  Why would a legitimate loan company call soliciting business?

they want $200 for the first payment for security

Why would you pay money to get money? This is known as an advance fee scam. They insist on money BEFORE you get your (nonexistent) money. It can be for any reason, that part isn't important. What's important is you going to give them $200.00 and then get nothing. All a scam. To ask for an advance fee to obtain a loan (for any reason) is illegal in every State of the USA.

So do you know anyone that has received the money
