Half packed order

I bought a family meal at 309 with order number 216 At Pedros Mams Square.I asked for 1 chicken cut in 8 and the other cut 4,they packed me 2x chickens cut in 8,the meal comes with a 1,5 cold drink that they also didn’t pack with my order. When i called in the manager didn’t even bother to apologise nor to ask to call me back since i was using my airtime, instead she told to drive all the way back to come and get a refund or collect a drink,customer service tried to call her but she said she was under rule that customers must come and collect whatever is short on their orders.Not even an apology whatsoever,Im very disappointed with the service i got.
