Cocacola — Cheating of offering my winning prize

Four days ago I got a message from cocacola company in U.K. that my email: [protected]@gmail.com has got a prize of 500000 ponds. So the authority informed me to apply for the prize stating bank details. So I applied according to the direction giving details about bank.. According to the proposal they had offer my prize to my account directly to my account to Bangladesh. But after I have applied they sent another message that the prize is not possible to deliver to bangladesh from U.K. So they informed me that they transferred the prize to bank in America in Delhi of India. And I am directed to contact with the authority of the bank . So I applied to the bank of Delhi yesterday for my prize. But they informed that the prize has not come for technical problems from U.K. so how can I get my prize .
