Winner on facebook competition - No one responding

hello nutriday<br> <br> I was announced a winner on your facebook, was asked to inbox my contact number and to date have not received a call regarding my winnings, I feel this is very unprofessional for such a big company. I've read through your terms and conditions, and it says payment will be made within 7 working days.<br> So why has no one contacted me?????<br> Please be so kind to contact me asap
