Airbnb negligence of customers

I cancelled my reservation for a place in Pattaya on the 8th of April on Airbnb. I cancelled a few seconds after the reservation was made because I realized after paying that the host was not transparent about the deposit.

Shortly after my cancellation, I received an email from Airbnb stating that I will get my full amount in 10 days time.

From payment of 6100.62 Thai Bhat, I only received 1000 Thai Bhat into my account.

I then contacted Airbnb to enquire about the rest of my money, Airbnb refered me to the host.

I contact the host, but the host declined my refund request.

I asked for intervention from Airbnb, but Airbnb is taking this matter lightly and not assisting me to get the rest of my money even though they emailed me on the 8th of April that I will get all my money back.
