Mr D doesn't have Nandos salad on the app

on 10 July, I tried to order a 1/4 chicken on Mr D with a Nandos salad as my side. For some very strange reason, the app has the choice of all the other sides except the salad. So I called the restaurant (Nando's Kosher - Savoy) to confirm that I can choose any side on the app, then call them to manually change it to a salad. I also asked (for the second time already) for them to get this issue fixed going forward. I received my meal, and they didn't even change it to the salad. I called and spoke to Mzo the manager on duty, who apologized and said he'd make sure it gets fixed. I then called 3 days later to ask if it had been fixed and he said that it hadn't yet, but he'd def escalate it. He even thanked me for following up efficiently and 'reminding' him'. 10 days later and I've heard nothing from him... Not ok for a manager to act like this...
