Who has deleted the sentence on my booking?

Who has deleted the sentence on my booking? We've booked 2 nights at the Montagu Country Hotel. On the booking and in their confirmation letter the following was included: Free WiFi is available in this room. Breakfast for 2 people: A breakfast buffet is included in your stay. When we arrived at the hotel, Reception told us, breakfast is not included. I said it was in the original booking. The hotel management was so nice - they wanted to give us breakfast for free - which I didn't want because I was 100% sure it was included. The hotel phoned hotels.com who said - breakfast was not included in this booking. When I phoned, I got the same answer. I then had to search for the confirmation letter that was sent to me on 10/09/21. As shown above, it was included. My question is, who has deleted that sentence and when? I tried to speak to hotels.com's customer care today, without success. I asked the consultant that the head of customer care phone me before the end of business today. It did not happen. That gave me no other option than to put this in the virtual domain to warn people. Be careful when you make a booking through hotels.com.
