Just recieved a call from Indian sounding lady.
Started by asking me to confirm my name which I never do as the opening stance of a call.
Then she went on to say she was from BT Broadband and was my internet all ok.
I challenged her without providing any information as to who I was, or whether I even had broadband to provide some evidence that she was legit. At which point she ended the call.
1471 showed her as calling from 08432 764071
