They are liars, and not accountable. Very poor service. They are basically a middle man providing zero service. Instead, they waste your time by providing wrong information and limit your options to change a reservation.
They provide very poor service, and at the same time, you get limited if you book through their website, as any changes you want to make to your booking has to go through them, then they eco it to the property, then the property decides, and Booking.com never notifies you about it.
Would have given them 0 stars if I could.
They promised me partial refund for 1 person's breakfast. They made the primise twice, two different agents made that promise on the phone when I called them two separate times. They told me in 2 weeks the property will refund me for that. It did not happened. I asked the agents who promised the definite refund to me, to send me an email confirming the partial refund, they said they did so and I never received an email. They assured me that there would be no problem if I ever follow up, and there is no need to have that email anyways. Now that I followed up after two weeks, they ask for the email proof. I would never use their website again.
I called them more than 4 times. They wasted my time for a total of 3 hours, and finally told me that the property does not accept to refund. I asked them to be responsible for what their agents promised me and process the refund from their end, and they refused to do so.
