Don't know if I'm getting paid for a cancelled risk-free reservation

My listing got booked for two night (26-27 September, 2019), and the reservation was marked as risk-free.

The guest cancelled during the free-cancellation window, and I was informed that BDC was looking for replacements. 

I did nothing to the room status so not to risk getting my payment if the room was not filled for those nights. I only have one room of that type. Eventually, BDC could not find any replacement and the room went unoccupied on both nights.

Now, I am checking when and how I am going to get the payment for those nights, and came across 2 statements on the booking detail page.

One says:

We sent you a bank transfer

Booking.com has collected THB 0 from the guest for this reservation. We sent you a bank transfer on October 15, 2019 – it could take up to 7 days to appear in your account.

Sounds good, but it has been more than 7 days and the amount has not appeared in my account

Then I scrolled down and expanded another box and found another statement that says:

Availability removed

Due to lack of availability, we stopped looking for a replacement guest and won't pay for this room night.

So now I don't know if I am getting paid for these 2 nights. If BDC refuses to pay on the ground that availability was removed preventing them from re-filling those nights, what evidence do I have against them to show that we did not remove availability?
