Hi,
We would like to shed light into this particular circumstance to clear anyone reading this of any confusion.
This particular client, indeed purchased a batch of used hardware from us, and we offered our standard 5-day DOA policy. We instructed the client to send us the SN's of the machines along with the reported issues, and send us back these machines for repair/replacement. Instead, the customer decided to undertake repairs on their own with a third-party repair center without seeking our prior approval, and without following our DOA procedure.
Unfortunately, we have clear steps defined for all DOA issues which often include repair, or replacement of units. In this case, said units would have been replaced upon receipt. We did not priorly discuss any unauthorized third-party repairs, and instead, we have been presented with an invoice after the fact. This being said, we had no way to verify that the repairs that have been done were performed on the hardware that was shipped out and not any other units, thus our DOA guidelines and policy.
We hope this helps clarify the situation.
