We have requested and received refunds for Batches 5 and 6. We have also processed and verified those orders which were submitted correctly on the form. The chip refund process has been delayed due to a large number of requests which have failed verification, duplicate requests, and phishing attempts. The bitcointalk forum thread will be updated with instructions for successfully submitting a signed message. We will be sending out refunds over the next few days, and will continue to process any future chip refunds requests.
Appreciate the updates, I think some of the duplicate requests may have stemmed from users with a different sending address for a subsequent chip order in the same batch. On the refund form, it allowed for different transaction IDs, but one single sending address (which makes sense since it needs to be signed), so an additional signed form was sent.
Thank you for coming through for the community, will be looking forward to updated instructions.
