Service ppl service

Kg can is so good with they adverts and marketing but when it comes to staff training clearly it's beyond average .this morning at 7.26 am I orderd a meal at kfc breakfast and spent about R107 so early to be given such service the meals I ordered took an extra 18:00 minutes to come out only to then receive my order incorrect then when I asked for my refund they refused and she was speaking at the back round waiting to be given my money back I'm very upset cause I support kfc even with its bad publicity I always spend above R100 donate R2 to charity but the service is not satisfactory .i want my money back please
