Dineout — Paid to wrong restaurant through dineout

I've paid bill amount(4448 INR) through dineout to wrong restaurant instead of the restaurant where we dined out and I've raised a ticket with number 515473 for refund request and dineout is still resolving this small issue since 72 hours and this is too ridiculous...and also I've been sending mails and had a too many chats with their support agents but no use till now

I hope dineout will take action on this
Thank you!
