I am sorry about your keyboard, but I can tell you I will never remove the logo from your keyboard, what good would do to me if I do so? If I knew that DHL would remove your logo, I would definitely let you know about that and rearrange the shipment for you. According to the logistic company, like I said before, your keyboard almost got confiscated by customs, but then they somehow talked DHL staff into letting your keyboard off the customs, but they did not mention a word that they would scrape off your logo. And it's impossible to get compensation from them since you have signed for the package already, which they consider that the deal is over, and they are not held responsible for any damage.
Even if you send back the package would not change anything, since this is not seller's fault.
I understand how you feel about this. And I would never wish such thing happen to you. And I am very glad that you are satisfied with my service. I can try to find a logo for you and have it shipped to you or else I am willing to give discount on your next purchases.
