No, Ben, I went back over everything again and again,and still it didn't work. So, forget it Ben.

Just please see that my CC is not charged Ben.

I have no interest in your services Ben for this PWCart.

Maybe later for something else but I doubt it Ben.

I find your service lazy and incomplete.

Your support arrogant and not very knowledgeable.

Looking forward to never seeing your name and company in my inbox again,

Richard
