You should've parked somewhere else free of any risk of being towed until 8:30 and then continued your normal procedure once the concierge returned. It's not rocket science, don't park where you're not supposed to park whether it's because 'the parking pass person wasn't around' or even if it's 'just for a minute.' This issue really bugs me, so I'm not exactly sympathetic.
Parking is consequence free until after midnight.
To everyone else, I'm not playing "damsel in distress" nor am I an idiot, and I am certainly not looking for sympathy - I'm not some whiny bitch, just genuinely curious as to whether it may be even remotely possible to get my money back. I've never been towed before and it just seemed like "it could never happen to me".
Thank you to everyone who has answered so far. I'm not counting my chickens yet, but the money somehow got recredited into my account after the fact ..... Soooooo maybe it's a Christmas miracle lol.
