Despicable Debonairs

I purchased a veg pizza in Nov 2021 and whilst eating I bit onto hard piece of plastic of which I took a pic. On the Famous Brands website I logged a complaint for which they never rep****. Very *********** and inefficient staff. Management hides behind the curtain and when I asked for email addr of the person in charge of customer affairs, they refer me to a backoffice email addr. I've spoken to several people on the customer desk and promises were made that they will attend to my issue - its more than a year and the staff are still fast asleep.
