No filling in triple decker!!!!!

I ordered a triple decker chicken pizza for my sons lockdown birthday on 22 May 2020 and we were fasting. The pizza arrived and as we about to break our fast there was hardly ANY filling on a triple decker which is supposed to be packed with filling hence the name!my word there was hardly any filling on pizza and just pastry and base. I took photos to prove my dissatisfaction and disappointment. Best part is I lodge formal complaint same night spoke to Emily at famous brands foods who noted it was lodged even sent her the pics and was told that debonairs wetton would contact me. It’s been 2 days later and still no feedback. Pathetic to say the least how do you treat customers this way is mind boggling! Also you pay so much for such terrible food and service!
