poor service and bad food

Bought my meal (Big Bite 3)...asked the lady who's name is Afrika to give me bigger pieces reason being I got ridiculous small pieces the previous day...waited for my order and finally the manager if he was a manager (very dark completion) called my order number 464..I opened my order to find the very same thing...told the guy but he jus ignored me as he was giving me my order...I walked away, came to complain to the other cashier and she just laughed and Afrika had nothing to say about my complaint. The chips had a funny taste as well, I even asked my colleagues to have a taste ...their service is very poor hence I will never eat hungry lion again.
