Zero customer service when hotels cancel your booking to jack up prices a few days out
The total lack of customer service means that if anything goes wrong there is no way to get support. Booked a hotel in Naples in advance of a trip over a long weekend, and then a few days out from the trip the hotel claimed they couldn't validate my credit card (we used three different cards to try and secure the booking, cards we've never had issues with in any place around the world) then cancelled the booking. The room then went back on the website at 3 times the price we had booked it for; they had clearly realised they could charge more over that holiday weekend so decided to cancel our booking. There's no kind of customer service with agoda to interact with to resolve this issue so we ended up having to book 2 beds in a hostel as there was limited availability in the city a few days out from a holiday weekend, and those handful of hotel rooms still available were massively marked up. It seems that there is no accountability for the hotels though agoda and they are able to cancel bookings on a whim and put the room back on the market at a much higher price and there is absolutely nothing you can do about it.
