This number keeps calling and hanging up. I have added it to my auto reject list

selling a holiday

The guy told me that I have won a 1000AUD voucher for holidays. He was talking to other people in a different language (Indian l believe) while talking to me; he was laughing and too rude to control himself.
I told him that I was not interested and other people have already called me about the same issue. While I was advising him to delete my phone number from their call list, he hung up on me!!!!! Soooooo Ruuuuuuude
