The thread might be locked. If the topic is locked, you can't do any actions there except giving merit(s) on posts on that thread. You will notice a lock icon besides the topic if it is locked.
If you wanted to make a feedback there, I guess it is okay to make a thread regarding on feedback for your successful transaction.
