I have already delivered the order but my buyer is not active and did not find any review. Time has expired . what should I do ??
An order is marked as complete after the order is marked as Delivered and then rated by a buyer. An order will be automatically marked as complete if not rated and no request for modification was submitted within 3 days after marked as Delivered.
The above is from the Terms of Service which you will find at the bottom of the Fiverr main page and contains the rules as to how Fiverr works.
TOS areso important, yet often they are not read.
