From pathetic to worse kfc service

KFC is really going from bad to worse with their customer service. I placed an order on the 29th of July 2023 that reached me an hour later then the delivery time after i had to call the store twice and them telling me they are struggling to get hold of the driver. I am a stage 4 cancer survivor and need to eat at certain times to drink tablets which I also informed them. They then sent me a R25 voucher which was not even 10% of my total I spent. Today I tried to use the voucher but no where on the online order website does it ask for a voucher and the most shocking part is there was no voucher number on the voucher. I called head office and the lady told me that their vouchers is up and they cannot issue me another voucher as she is able to see that my voucher had no code with it. HOW PATHETIC IS THAT. I told her if she could not call the store before they delivered my meal just to add a milkshake which is less then R25 and she said no they are not able to. I am in shock.

Disgusted!!!
