I bought Session Guitarist: Electric Mint and started downloading the instrument, until I realised that I could upgrade to Kontakt 8 for the same price and receive a £89 voucher with purchase which would allow me to get Session Guitarist: Electric Mint for free.
I have put in a request for refund but I got an automated reply saying that I can't get a refund as it is a digital product.
https://support.native-instruments.com/hc/en-us/articles/209568149-I-would-like-to-request-a-return-or-refund says "If you haven’t registered or used the product, exceptions can be made." which would counteract the automated reply.
