I called back number (02) 8378 7914 rang once then gets disconnected automatically.

Sam call, said will refund money to me

Scammer

Caller: Don’t know

Rang hung up. Scam

It’s a scam call. Called saying they were from Think Markets and that they’re shutting down (I have an account with Think Markets) said she will send me an email and I need to be near my computer and I will get a refund and 3 bitcoins as they had a dodgy broker. I called the real think markets and it’s a scam. Do not engage

Caller says he’s from Blockchain in the UK and wants to return my money. But then states that he needs me to open the website AnyDesk.com so he can see my bank accounts to check for money laundering. This is the second time that he has tried this within a week.

Scam call

I answered..no one spoke.
I called back, no one answered just kept ringing.
I don't know who or what it is but they have called so many times & I get nothing.
