Cramer Airport Parking

Service to and from the airport was great. However upon returning I was charged $8/day ,My preregistration,sku 01000184 has my cost as $7/day as a frequent parker.Upon returning home I emailed Cramer asking why. No reply. Emailed again 4 days later,no reply.Did receive a reply both times that email was received and they would get back to me.If you park and have a registration make sure you know what it is and only pay that amount.
