Dear 

Thank you for contacting Optus Stadium, I'm sorry that you were disappointed with the INSERT ITEM  that you purchased from us. 

If you experience any problems with food or beverages at Optus Stadium during an event, the recommended course of action is to return to the outlet you purchased the item from so that staff have the opportunity to rectify any problems there and then. 

I will pass on your feedback to our Retail Food & Beverage management team regarding your experience, thank you for bringing this to our attention.
