I ordered two maps from Omnimap.com. One came after not too long, and the other was on back order until after I returned from my trip a month or two later. Before I left on my trip I emailed them and asked them to cancel my order for the second map and refund my money. No response. After I received the second map (which was after I returned from my trip) I emailed and called them several times to ask them how I can return the map and never received a response.
