Disappointing Service from Flight Centre

I planned a holiday with my husband for January 2023 to Mauritius using Flight Centre Kolonnade as our travel agent. We provided the list of our preferred hotels and picked one, and the agent confirmed that our booking had been finalized and confirmed with the hotel. A few days later, we were called and told that the hotel we picked was no longer available, and we were given the option of a hotel, which we declined as it had no similarities at all with the hotel that we picked. A few days later, two other hotels were added to the list, which we picked, and we really enjoyed our stay. We decided that we would like to visit Indonesia (Bali) in September 2023, but with our past experience with Flight Centre Kolonnade, we decided to use Flight Centre Brooklyn. We were booked in Ubud for 2 nights and 4 nights in Nusa Dua. The agent, however, booked us for 5 nights and informed us that it was a system error and we were charged for the 5th night. Her explanation was that it was due to the 5 p.m. late checkout as the hotel checkout is at 10 a.m.; however, the hotel check-out was at 12 p.m. and not 10 a.m. (Clearly, bookings are being made with no information from hotels). The hotel confirmed that we could have been accommodated for an additional 5 hours for free if the agency had communicated accordingly. Very disappointing for the money we pay.
