Who called from 6263462569

Received a call which I didn't pick-up.  No message left.  Called back next day and it seems to be some energy company selling solar...ougoing message sounded like "America for Energy" or something like that.  Blocked.

Called and left no message. Another spammer to block.

They called and I answered, I said "hello" twice because it was dead silent and then they hung up.

I didn't answer, they left no msg..
