I bought one constellation map because I wanted for a gift. I needed right away so I pay for download it. Once I paid, nothing happened (any bottom to click or coming back or nothing, the screen was static). I was waiting an image or a link for downloaded, so basically I paid for something I didn’t receive. I tried to contact them in the telephone number that was in the bill that I paid and nothing, there is not a contact number or mail or any way to contact with customer service. They have the option in the page of “saving map” (so you can come back and buy it). It was through thatI could contact them, but lasted too much in reply. I had to buy other thing for the present. I basically lost my money.
