Paid for food we did not receive

I make use of MR D delivery app, and today I ordered the share meal from kfc, which includes 6 pieces of chicken, two bucket for one's and 12 nuggets, when my food was delivered there was only chips in the buckets, and its supposed to be chips, one piece of chicken and two zinger wings. We pay alot of money for food and only receive half our order. Its very disappointing. Next time i will order from somewhere else.
