The items I bought were not delivered (Amazon)
In most cases, this is simply a matter of slow delivery. If you have not immediately received your items, just wait a couple of hours and all should be okay. If nothing happens, please contact Amazon support (https://www.amazon.com/gp/help/customer/display.html) to find out the status of your purchase and request a refund if necessary. Unfortunately, we are unable to refund your money ourselves or give you the items you haven’t received, as we do not handle the transactions on Amazon.
