Very dishonest

I own and operate two establishments. Last week we had a guest book through Agoda. The booking was confirmed by all parties and the guest was billed (and paid) the full amount. The guest was due at 1pm, but we had no way of contacting the guest as no details were forwarded to ourselves. When the guest had not arrived by 8pm, I sent an email to Agoda stating that the guest was a no-show, the guest then did arrive at 9pm. I then immediately sent a second email to Agoda to inform them that the guest had arrived and that the booking should be reinstated. After three nights, the guest departed amicably, I have emailed Agoda numerous times to inform them that the guest completed his stay and that we wanted to claim our payment from the company. Yesterday, I received an appalling, rude and very condescending email informing me that the booking had been cancelled and that Agoda will NOT be paying me for the guest's accommodation, and neither will the guest be issued a refund on his "canceled" reservation. This is theft in any language. I looked online and see they have hundreds of complaints against them for similar issues We will not be dealing with Agoda again and advise other parties to think twice before doing so.
