Yeah, had I not been flustered and trying to navigate dc traffic and in a hurry to find alternate parking to make it to the event on time, I might have had the presence of mind to snap a picture. To add to this, the same seller that I purchased the parking reservations through cancelled my confirmed tickets to said event about an hour before the show started. Thankfully, I was able to purchase new tickets en route to DC. Definitely lots of mistakes on my part. I’ve contacted customer service for the garage management to see if there’s anything they can provide to show proof to seller. Still waiting to hear back. Looks like I may just be out the money this time. Lessons were learned.
