Yeah, fuck Dollar Rental for not policing up the shit you left on their property and returning it to you post-haste. Seriously, if you rented a car that means you are at least 25 years old, making you grown up enough to remember your belongings. But no, its way easier to blame a faceless customer service rep for your fuck-up.
I'm so sorry that Dollar Rental didn't treat you like they were a helicopter mom and you were their pathetic fucking child that still pisses his pants in 6th grade.
Stupid fucking complaint.
