Who called from 6466321129

I won $6700.00 and I needed to call this number to speak with a senior sale manager to receive my money.

Recieved a call that i won 6,700 and was told to call this number and.then they asked me for 250 dollars

Received a call that I was being given a government grant of 6700 $ and I would receive it through Walgreens. I was to call this number to speak to the manager and make arrangements to receive it. Been afraid to call it.

Received the same call specifying O was approved for a IS Gov grant on 6,700 total. Also told to send &250 and would be reimbursed. Haven't called back yet. Said the 250 was a state to state transfer fee because I never applied for a grant. Unsure..

Has anyone further investigated this.
