I tried to book a night in Bangkok. The app said every single hotel was unavailable for any night in July for any BKK hotel I tried over a 2 hour period. Next day I tried again and there was availability everywhere. Obviously a tech issue

I emailed CS with a complaint about the technical issues and they said all hotels must have been booked then. Do these CS people have a clue? Especially when I said the next day when I tried it showed availability everywhere.

I will switch to Hyatt as I have done this trip in Doha and Addis Ababa. I am too frustrated with the continuing IT issues (they have gotten better to be fair) and the ongoing terrible customer service which remains deplorable.

I understand technical issues that no one wants but why can't Marriott get trained CS agents
