Caller: Some one stating they are calling from amazon sercurity

They mentioned some one was trying to purchase a phone from Amazon and had made a fake account under my name. They wanted me to put the phone on loud speaker then asked me what phone am I using. I told them if your from Amazon just block the purchase and you don't need to know what phone I used or if my phone is on loud speaker especially if you can hear me talking the whole time BLOODY SCAMMERS
