Price was stated in the full amount instead of discounted one.
As employee of WG I have discounted price and that is OK, I was charged for the correct one at first. But Full pricing has been stated on the customs, so I had to pay customs as well. With discounted price I was not supposed to pay for the customs. Also, DHL handed over my package to the local post, so I had to pay that as well. And they were on strike, so I had to wait weeks longer than usual.
