I have.
Yes, I admit it - I have left a Neg for a seller without having paid..... but there is a reason.
Despite several requests, they never gave me a total amount to pay, so that made it hard. Then again, I found out they didn't actually have the item on hand when it was sold - nor for the following 6 plus weeks I waited.
Was I unfair? If so, what should I have done?
Has anyone else had any similar situations?
