Poor response and refusal of refund

I purchased 2 vouchers from Groupon in December. I received an email a few days later stating that the merchant was unable to honour the offer. <br> The day I received the notice that they were unable to honour the voucher, I emailed the email address provided by Groupon wanting to enquire about my refund. This email address belonged to Groupon USA & Canada! At least they were kind enough to respond the same day providing me with the correct email address. <br> <br> I then immediately emailed Groupon SA asking for the refund into my bank account, and waited days for a response. <br> Eventually after having to go on social media, I finally got a refund - for the ONE voucher!<br> I then emailed again asking where the 2nd refund was and was told that it fell outside of the 7 day cancellation period (even though I had not cancelled anything, which Angelique should have known due to our email correspondence) and was told it will only be refunded as Groupon credits! I do not want credits, I just want my money back on a deal that Groupon's merchant could not honour.<br> I have had to send countless emails trying to get MY money back waiting days on end for a response from them. This is a waste of my time.
