Unprofessional Behaviour

coke agreed to sponsor our fundraiser evwent on 15 dec 2015 with a sound truck and stage, we have been calling everyday waiting for the confirmation email and everytime we spoke to bradley in the events department he keeps saying tomorrow and today when i called he said he only received the email last week which is a lie, we have sent the email looking for sponsor months ago. this is putred as we are raising funds for a needy instatution and Coke is unable to help after they have already confirmed to help
