I've even tried working cvv with correct billing and still get this message on a shop!
Does anyone here have suggestions or give a bin that can defeat this?

I suspect the CVV is just invalid (usual case these days if you use autoshop to buy them) or low bal/incorrect billing address or your IP/system isn't clean and is detected.
The error message suggests that it could be store's problem as well but it is not likely. Maybe some one else knows better, I've never seen this exact message with any merchant I know of.

thx 4 feedback Bultron but I've tried same cvv on several other shops and works fine! So I think it's IP ban or shop error like you say but not sure :/
