Poor costumer care and service

On the 6th of March a made a order and payment on the online shop. I received no correspondence fir the order of the payment. On Monday the 9th of March I phoned aslnd they said that they dont have any products in stock but that they will be in contact with me before the 13th of March. Today, 16th March, I phoned and there is nog answer and they dont respond to any of my emails! This is really poor costumer care and service!

Why do they let you order and pay online if they do not have any stock?
