Order Discrepancy & Customer Service Failure

I honestly don't appreciate how they handle issues. I ordered 10 Zinger wings and streetwise 2 on the KFC App on the 1st September. I received a link from Uber to track my order. Seemed like the driver went somewhere else first, but my ETA kept moving forward. When i finally received my order, I got 4 Zinger wings. Communicated this immediately on received REF no's as per usual and no feedback until today.
