They have a sht policy to cancel an order.
You have 3h OR until the order was confirmed, and in my case, the order was confirmed in 3 min, I didn't even have time to look on the order details. Please try to avoid this store as they are trying to not help you with anything, the support it's really slow and the only communication channel it's via email, on Facebook nobody answers there.
I can understand now why the items are really cheap compared to other stores, because support it's not existing, basically this is a platform where anyone can sale their product even if it doesn't correspond to the description.
