Buyer asked for revision but didn't give anything to work on, what can I do?

Hey everybody! Hope you're doing great.

I have the following situation. I delivered an order a day ago consisting in three songs that I had to record (I'm a musician). I just got a revision request from the buyer but he didn't give me any feedback to work on. Actually, he "Wanted more time to check the songs properly with all the guys in his band". As a result of a similar case in a previous order, I had a downgrade in the exposure on my gig and I don't want to suffer it again, specially when I have nothing to do or it's not my faul at all. Is there anything I can do? I already explained the situation and sent a delivery time extension, but I had no answer yet.

Looking forward to your input. Thank you so much!
