I requested two vouchers with my gift card, but one contained an error code (RDMx3) meaning that I couldn't decrypt it, and the other one didn't come through at all. I contacted Every Wish about it, and after 3 or 4 days the voucher I was missing came through without any explanation. It's supposed to be 1 hour. I had to chase them again for the other one, and they eventually sent it in a different format that didn't require decrypting. There was again no explanation as to what the problem was. In fact, they said to contact the retailer directly if I had any questions. I found that surprising, that they would sell these gift cards but then tell you that redeeming them was essentially nothing to do with them. Also, by the time I got the vouchers, the time to use them had been and gone, and they were no longer useful to me, so...
Response to their reply: I don't need to contact you, thank you. I eventually received the vouchers as per the above and this is my feedback on the experience.
