Need some advice

I have recently sold the user 'Clock' (who is now banned for multiple scamming) 500m 07 for UKBT. He has admitted on this post:

http://www.sythe.org/oldschool-runescape-selling/1895515-selling-1b-07gp-1-1-m-btc-ukbt.html

that he has been on a Romanian IP for the past month selling/buying 07 gp via UKBT. Is it possible that I will suffer a chargeback? What are the chances? What should I do? Do I call my bank before he tries anything?

Thanks for the help in advance!

EDIT: I might have post this in the wrong section! Bare with me.

I made a post on your post regarding this in general discussion.

In future, don't make a double thread, just PM staff/report the post to move it.
