The best restaurants serving Fast food food in St Johns Fylde North West

I went for a drive through in October for a family of 3 they missed off a burger and a share box. One I got home and realised I phoned them. They advised either come back and collect or they will give me a code to collect next visit. 01-11-24 went again to retrieve and they advised my code was invalid. Tried phoning 6 times with no answer tonight. Terrible service let alone terrible customer service. I see this as theft paying for something I haven’t received or will receive.
