Lack of Customer Care from KFC, No Communication, Issue logged Nov 2*** and no phone call ever recived

In attempt to help my sister celebrate her birthday with her kids, I went KFC online to order a voucher for them (This was in Nov 22 2023) I attempted about 3 times but the KFC site kept telling unsuccessful or network error. So my understanding was that voucher wasn't purchased. Next day Nov 2023 while checking my email, I find an email that a voucher was purchased.

Problem: I guess due to multiple attempts I made, I made a mistake in the number I provided for the voucher. Which means my sister did not receive the voucher but my money was deducted.

Since I have logged calls and made numerous calls to KFC and KFC has done nothing. I even told them that I don't need a refund, they can just correct the number - NO, KFC has just ignore. No call received and when I call they say they will contact the relevant team and call me back - They never call

Now, I just called again, and I'm told the only interaction they see made between Customer Care and the responsible team was in Dec but I have been calling Customer Care twice to 3 times a Month.

Latest information as of today 5th April 2024, is that the responsible team has told the Customer Care team that they can not find the tracking number. The tracking number is on the automated email sent to me by KFC, so how does KFC not find their own tracking number that they sent????

Makes me question KFC's sense of Customer Care!!!
