RMA REQ SENT

Hi Christopher
I have now refunded your card for the discs you have returned (I refunded you for all 20 even though one disc was opened, rendering the 2nd pack unsellable by us).
You should receive an email from Worldpay confirming the refund, and please note this ticket will now be closed.
Kind regards,
