Caller: Fake Paypal

I received an email from "PayPal" and I use that term loosely. CLaiming they were going to take $699.99 from my account and that there had been severa attempts to take money with this particular accoutn that they had screened. So contact the number to verify it was fraud.
Only problem is I don't have an account with that particular email address lol. So I rang the number to see what they would say, and is what a call center in India claiming to be PayPal. Which they are not.
Be careful people these scammers are getting smarter.

Caller: Scammer

I rang them and they ask me to type in a website address to cancel that payment.
Luckily, that I smell bullsh*t there.
Be careful everyone. If we follow their instructions they will hack our server and you know what will they do,
So just ignore and DO NOT ACCEPT TO SEND MONEY.
After few hour they has cancel their payment request.

Thanks received same message today, so I did not call back
