Unwillingness to help and uninterested management

I visited KFC in dawn park on the the 24th of Dec 17. I specifically asked for a special request and I was told it would be done, after I had paid I was told that what I asked for is not available, I requested a refund only to notice I was charged R143 for something which was only supposed to be R45. I queried this and a refund was performed electronically. Today, I went to go find out about my refund which has not cleared in my bank and asked for the manager on duty. The manager did not avail herself instead she sent over a guy which had no interest in helping me. How do I as a customer feel valued when even the manager has no interest in dealing with the shops customer? The service at this particular KFC shows no value of KFC and does not live up to the brand's mission statement. I will not be surprised if I don't even get feedback on this. I'm just alerting consumers know this is the last outlet they would want to visit.
