KFC is a disappointment!

I recently placed an order at our local KFC, however afer ordering zinger burgers and zinger wings on the app, I arrived at KFC and was told that they did not have burger buns or lettuce and I was given two wraps with only chicken and sauce on as for the zinger wings it was completely dry and tasteless. This was a complete waste of my hard earned money. I then gave KFC my feedback in a complaint, however till today I still have not received any feedback. Their level of service is ridiculous and I'm extremely disappointed.
