Hi, we received a parking fine letter. It was from a hotel (what a shitty hotel, we had a meeting there, but apparently didn't validate the parking correctly), but it looks like they already passed it to a debt collector company who added a significant admin fee on top of it. We emailed the company asking to give more information about this fine. They replied back saying the original fine was issued last year, and since then they added additional admin fee and late payment fee. I checked the original fine attachment. I have never seen this letter before. They did not put my unit number on it, so probably this is the reason we haven't received it. I am happy to pay the parking fine, but I am not willing to pay for any additional fees. How should I proceed? Is it safe/wise to fight with these guys? Please see letter attached.
