A scratchy arrow key

Hi. Thanks for asking. Here is what has happened (and I have mention these events elsewhere on the forum).

Framework sent me multiple new input covers. Each had the same scratchy key. Now the support people are asking me to send the machine in for repair, even though I have discovered, and communicated to support, that the defect - where present - manifests itself in the keyboard even before one has attached the input cover. That is: Framework needs to fix a keyboard and send me the fixed keyboard; but Framework insists on having my computer in for repair.
