Two calls received today - first one was a heavily accented person asking for someone whos name i didn't know. The second call i answered and it hung up.
Tried calling the number back and it's disconnected.

Missed call. No message left.

Twice i have received this call, first time i answer, they asked for someone, not my name,

today it rang again, i did not answer.

Rang here so I tried to call back and same result ..busy (probably a call centre )

Silent when answered, buzzed, then hung up.

Annoying spammer

Caller: I don't know

return call but always busy
