Hotéis Fairfield by Marriott em Visalia

Due to Covid-19, we did not travel for about 2 years. As of Apr, I had 4 free nights, three expire in Jun and one expires in Dec. I booked 2 nights at this hotel from Apr 17 to 19 with free nights. When arrived, we found that pool was not in service. My kids got really upset. One main reason I booked the hotel is indoor pool. They did not state that either on the web or app. In the night, I called Marriott to see whether they can switch the second night to residence inn. I called residence inn and confirmed pool working. The lady told me everything was set and I was going to get cancellation for Fairfield inn and confirmation letter for residence inn. I got confirmation letter in minutes but no cancellation. I called again and was told me since I was in the hotel so I had to talk to front desk to cancel. I went downstairs and chatted with front desk. The lady told me she would let manager know and everything was supposed to set by 8am next day. Next day I still did not get cancellation letter so came by front desk during breakfast. They promised again manager would handle it. Around 9am, we tried to checkout but Marriott system did not allow since it still showed as 2 days reservation. Front desk promised that they would handle it by 12pm and posted points to my accounts. It would take 2 to 3 business days. And two days later, finally my second night of Fairfield inn got cancelled but no points or free night was not posted. While stayed in residence inn, I booked second night with free night that expired in Dec. After one week, I contacted Marriott again. This time, a gentleman told me that there was no much hotel could do. He posted free night expire in Jun. I asked for free night expire in Dec or points since we do not have Jun trip plan. If Marriott did not mess up, for sure I will use Jun free night instead of Dec free night. He told me that's it and he thought the lady did everything right. Really got exhausted. For a simple problem, it took hours, calls and chats to fix. And finally got messed up and customer has to accept it. looks nice and professional but no one can help. Everyone promised but no promise really happened.
