Trying to make parking arrangements for the Paul McCartney concert coming up on May 28th. I have signed up an account with prked.zendesk.com/ 3 days ago and still have not heard back about requested information on how to obtain parking through this company. I have submitted my credit card information as well as setting up an account with a password and nobody responds back. I need to get information on where and how to park at the Camping World stadium in Orlando Florida for the event taking place on May 28th for the Paul McCartney concert. It's pretty simple but not getting back with me is making it difficult. I am trying to do the best I can by fulfilling the requirements requested by this company and still have not heard back from them. If anybody has any suggestions on what else I can do I am open to suggestions that might help me further accomplished my goal. Thank you very much.
