Afternic domain sale issue

I listed a domain for sale at Afternic for high x,xxx. There was an email from Afternic partnersale saying there was an offer below the listing price which I accepted.

Afternic is saying they have prompted the buyer to make payment but it hasn’t happened for 36 hours. Afternic reduced the domain price for the buyer to purchase but it hasn’t happened.

With Sedo, they have records of offers on their system and not with Afternic? Just emails?
