The best restaurants serving Fast food food in Walton Central Elmbridge South East

My delivery order was missing a double big mac (aprox 9£). Ive tried for over an hour through various methods to get in touch. The number in the message didn't connect me, its impossible through the app as the virtual assistant doesn't connect you, ive tried numbers found on Google, on their website, etc. It didn't work and it ruined my evening. And i will probably never get a refund. I'll never order from them again. EDIT. At a later date when i visited the McDonalds in Walton, i have told the manager what happened and he offered a meal of the same value in place of the double big mac as they didn't have it available.
