We are Diamond Select and have NEVER had worse customer service. We booked on the Best Western App at Senior rate and paid $100 of $111.33 rate. When we arrived Serenity refused to check us in and give us our key. She said demanded $40 additional and she would not honor our rate. She kept muttering the taxes were more than we paid. Unbeknownst to us she also took 20,000 points from our account (revealed by customer service when I called the National Reservation line for assistance. We were driving cross country, it was late and we were tired. It took me an hour of disagreeing with her and finally 45 minutes speaking to the National reservation line to get our key. The entire time other guests were trying to check in listening to her untruthful, condescending comments. Some walk-in guests chose not to stay when they overheard her demanding more $$ after we had paid, plus taken our points. She refused to allow us to cancel and go somewhere else. While she spoke to telephone reservation agent who trained her to get the computer to accept our rate, she continually lied to her about what had happened. Throughout the 1 hr delay we waited to get our key she argued with us in front of guests. She topped it off by responding to my inquiry of what is your name, with "my name is Serenity, it means Peace just to put one more arrogant comment out there. Just in case that wasn't enough to spoil our stay the housekeepers started banging on our door at 8:30 am to see if we were inside. We yelled through the door 3 times we were still there, but they were laughing and chatting so loud they couldn't hear so they continued banging. I had tto stop packing and go open the door to get them to leave. When we did leave they had left 3 housekeeping carts in front of our door blocking our path to the lobby To top off our stay it took me 50 to wait for Asst to manager to show up 20 minutes late and 30 minute discussion about all the ruckus. Once we left Customer Affairs called me and that took another 25 minutes. If you have 2.25 HOURS spare time to have unpleasant conversations on your vacation, PLEASE STAY HERE. YOU'LL LOVE IT.
