KFC Incompetence

The KFC App is a JOKE!. On 31 May we placed an online order for a simple meal. after about 3 hours and many calls later the order was cancelled and I was promised a refund. I received no response from my online complaint on the system so I resorted to messaging them via their Facebook platform. The whole of June I was insistent on receiving my fund. Eventually I received a Proof of Payment from them (not once a word of apology mind you!). On closer inspection the status of the POP looked odd and surprise surprise - it has still not reflected in my account. The question I am asking myself now - is it incompetence that they dont know how to do refunds or are they trying to ***** from Joe Public?
