Most humiliating experience buying food EVER!

I am appalled by the service I received from your Customer care when KFC Promenade drive through called them regarding my old mutual voucher to the value of R127! There was loadshedding so the voucher did not read from kfc side but it still deducted! Now the value of the voucher is R3.20 they took R49.90 for a streetwise 3, R69.90 for 10 zinger wings and donated R4 towards feeding the kids! The customer care consultant Lucia was suppose to assist but was so extremely rude, she refused me from speaking to a manager and then dropped the line! She said she will re-in state my voucher, would be active in 24hrs that was Saturday 21 May 2022 and it has yet to be reinstated and no communication has been received since! I was at that store for almost 2hrs! My complaint has still not been resolved! I was humiliated in from of your kfc staff and customers that were there! I spent my petrol driving to that kfc for nothing and slept without food since it was loadshedding! Never have I ever had such a demeaning experience trying to buy food! I want my voucher back! R127 voucher the full amount immediately! I Have sent multiple messages to the KFC "CUSTOMER CARE" And have yet to receive a resolution for my complaint! I WANT MY R127 VOUCHER BACK!
