Irate

I’ve placed an order using the KFC app..order advised that it has been delivered within 5min of placing an order.i called the contact centre and asked to speak to the manager.I was given a manager by the name of Busisiwe however she was no help.she kept on saying there’s none they can do.I insisted on a voucher to place another order she advised that she doesn’t have voucher I then asked to speak to someone above she advised whoever who’s above her will give me a call in 2min I guess that was a way of getting rid of a hungry,irate client. Very disappointed with the kfc app.All I ask for is to be reimbursed my money!!!!
