It used to be easy to edit a listing now it appears that you are limited to being able to change the title only.How can I change the auction period from 5 days to 10 days for example. Or change the postage from pick up only to will post?Thanks
lCustomer has not made contact. Has not responded to the two emails I have sent and it has been 5 days since they paid for item. What should I do.
