KFC not honest and does not refund you when they cancel a order

I ordered online on the KFC app. Paid R363. They sent me an email saying its on it way and then they cancelled. They told me they will refund me this was in May. Today is the 20th of June still no refund. Thank you for contacting KFC Customer Care Your reference number is CAS *** M0P2T6 A KFC Customer Care Representative will be in contact with you They never phoned me back nothing. I will now make a big Scene because R363 is a lot of money for me
