Hello this is admin of cardvilla.net i would like to answer some of our questions, i personally do not sell anything because i am not seller and people you see selling things in VERIFIED SELLER section are all trusted and verified by myself after testing their product so i take personal guarantee of them and take full responsibility if anything goes bad.
You can see or read customer feedback in their topic or escrow section
we do not allow to use third party escrow because Escrow team in our forum is independent and they never make mistake,
myself as admin seen people deal with d4rk-s0urc3 and they all were happy so i vouch for him
