My apologies if this topic has already been address but I can't find my exact query. I took a book order to the Post office ( paid Royal mail postage- not through Amazon) and by the time I got back the order was cancelled. I looked through the Amazon help pages and could not find out quite what to do in this circumstance, so I marked as shipped and then thought I ought to contact the buyer to apologise and explain. The contact options had been blanked out, so I contacted seller support who referred me to customer services, who sent me back to seller support. It is obvious to me now that I should have marked as dispatched before I actually sent it, but we very rarely get cancellations and this has never arisen before. ( mea culpa). Does anyone know how to contact a buyer once the item has been marked as dispatched without incurring the wrath of Amazon??? Thanks....
