Yesterday night I placed a Domino pizza order via Grabfood. Waited for hours and end up Grab completing my order and charged me even though I did not receive my order. Contacted Grab and told me that Domino's used Grab platform to get the order but they use their own delivery partner to send the order. Grab support advised me to check with Domino's and they're the ones who can process my refund. I've been reaching to Domino's customer care hotline since yesterday but no one picks up, keep saying all their customer service officers are busy. What should I do to get my refund back? Should I lodge a report to KPDN?
