Who called from 4084718914

they keep calling and dont leave message

Somebody tried to get me to buy ticket for some non-profit event.
It appeared like a scam, because he asked me to provide mailing address(so that he can send me tickets) and credit card number.  He also said that I would have to do transactions over the phone, no online transaction.

Do not give your credit card number, name OR address to any random dude who calls or emails or mails you.

Said that due to technical difficulties, they were unable to speak with me directly. That was the whole message.

Left message "Please accept our sincere apologies."  This seems to be a caller id spoof as they keep calling with different numbers as I block them.

when answered by answering machine, a recorded message says "I can't speak with you in person right now..."  I get these calls a lot, often from different numbers.
