Kfc Phillip Nell park

I wrote to KFC about an issue I had about mash and gravy which a I requested but received less but I'm not paid back and are treated like nothing I will not enrich staff nor management at any KFC branch ,and the person who contacted me was not serious ,about the complaint,it's just a little mash and gravy,at the end it's thousands of customers,who pays for a product but received less,it's ***** , they're *****ing.it's as if they know that there is *******ion in their KFC takeaway branches ,staff score out of customers and management looks the other way ,unfair enrichment.
