Refund pending

Purchased a voucher on the 13th May, submitted a request for refund a few hours later on the very same day, received an email 3 days later advising I could get credit but I'd like my monetary refund, per the refunds guide if contacted within 7 days, I may receive this, seems now you're dragging your feet with completing this, probably to have it expire outside of the 7 days. I have made 4 attempts of contact to your support desk.
