Looking at the order record in our shopping cart, it was sent by ordinary air mail the very next day after the order was placed. We never received any complaints about non-receipt from this customer.
In the meantime, our shop has now closed ans we have surrendered our merchant account. I am wondereing what you may do in our situation? I am really quite shocked about this since the customer runs an e-commerce shop himself.
I am not sure we should entertain this enquiry and I don't think there is anything he can do about it. Since we do not intend to run our shop again, our reputation is not at stake.
