Hotel Holiday Inn Express a Lenoir City

Made 2 reservations for a total of 3 nights from 10/12-10/15. Two nights were paying and the 3rd night used my free Chase Anniversary night. I called the hotel on 10/10 in the AM to verify the 2 reservations and the manager said she located both and would merge both together. I wanted to verify this would be seemless and no confusion on check-in, and she said I was all set. Well, on 10/12 in the AM, while driving to the hotel, they called me to verify I was still planning to check-in in on 10/14 for 1 night. I said I had 3 nights reserved and the rep then seemed confused and put the manager on the phone. She was immediately very argumentative and rude with me. She was asking what room type I had reserved for the 1 night, I told her I wasn't sure as I was driving, but that I called on 10/10 for this exact reason to make sure there were no problems and I was told everything was merged and good to go. She demanded who I talked to on that call on 10/10, and then she admitted it was her. She said I would have to check out of my current room on Saturday, and check back in to another room since I had 2 different room types and they didnt have a same room available. I told her I was going to be gone all day for the event I was in town for and what I should do with my items. She said I could leave them in her office when checking out Saturday AM. I told her I would just lock in my car and then she rudely said, ”versus leaving them in my locked office? Okay, that doesn't make much sense.” At that point I was getting frustrated and told her based on prior 10/10 call with her that everything ”was merged and good to go”, didn't trust my items would be safe in her possession. Overall just a bad experience. That phone on 10/12 on their part was hoping I wasn't showing, because they knew they lied about 10/10 phone call, otherwise, why didn't I get a call to confirm the 2 prior days as well? Also, no Platinum Elite recognition on either check-ins, bad mattress that were way to soft, stained sheets, dirty bathrooms, and a very awkward location.
