Who called from 2065084014

Just saw this caller attempt to contact my phone.  I did not answer, but contacted Amazon immediately.  Someone had gained access to my account & tried to purchase electronics through my account.
They were attempting to have it shipped to:
WILLIAM CALDWELL
248 SOUTH GLADIO TRAIL
PANAMA CITY BEACH, FL 32407

Called three times one right after another. Blocked before they could call again. Caller ID "SEATTLE WA".

I also received a call from this number (which I didn't answer) shortly after ordering a pricey camera lens from a third-party seller on Amazon.  I called Amazon Customer Service to report it, and they weren't interested in hearing about it -- just gave my bland assurances about their security precautions and didn't even bother asking for the phone number.

I just got a called from these criminals trying to be Amazon. I gave them no information and hung the phone up.

Bought something expensive on amazon and almost immediately got the call.  Did not pick up and contacted amazon customer service - they did not seem to know any history associated with the phone number and assured me that they did not initiate the call.  My question is how are they getting personal info  (phone number, order history) from amazon's "secure server, blah blah blah"??  Doesn't make me feel very safe.
