Who called from 7133576924

They said can you hear me. I said yes and who is this. And they said hello again and that this is the fbs and then I hung up.

This is the 3rd call fom this number.  They do not leave a message.  Is this a scam?

3rd call did not leave message any time.

I called back they said FTX services... no idea what it is, but I bet a scam.

They called and asked to speak to the owner of the number. Told them I was busy and wasn't willing to talk and hung up. The man's voice was foreign with heavy accent. Obviously a scam.
