Best Western Cottonwood Inn

I have terrible experience with this hotel. I am a very clean person, no drink, no smoke and no pet. I only stayed there one night, kept the clean as it was, but hotel charged me $300 after I left this hotel. They claimed that I had pet pee on their carpet. I even think this is how they make money just make a lie to charge customer. I have called back to try to communicate with their manager, I left a message since the manager didn’t pick up the phone. I have never heard from the manager yet, and I called back again, their number wasn’t exist any more. It was so bizarre. I will never stay any Best Western hotel. I will sue this hotel for something I have nothing to do with it.
