CAUTION: There is a current phone scam involving H&C insurance.
First, there will be a call come through to your number, likely from Sri Lanka, but could be from anywhere. If you answer it, your number will be registered as active.
Second, you will get a call from a local number saying that it's XXXXX insurance company calling because there is a problem with policy renewal and you may be uninsured. They will ask you to identify yourself with the normal processes - they sound very authentic. I gave them a fake date because I wanted to see what data they had on me. They had my name, phone number, email address and an address from about 8 years ago.
I assume from that point, they will get your CC or account details and ask for an immediate payment to ensure that you are not uninsured.
I answered the call from Sri Lanka as I wanted to check the scam out. But if you don't want to be bothered by the scammers, don't answer calls from Sri Lanka or other countries were you don't know anyone. This might be a relatively old scam, I only became aware of it a week ago.
