Pathetic service from KFC

This was the second time we ordered online on the app. The first time our order was cancelled without any feedback and we just received notification on app that order was cancelled. The second time we ordered, I phoned the call centre to follow up. The first agent advised that she could not get through to the specific shop and she will revert back as soon as she can get hold of them. Half an hour later I followed up again and was advised that they do not have enough drivers. My order was placed at 18:55 and the second time I followed up was 20:30. Since they were having driver issues they advised that my order will be cancelled and that the refund will take 7 to 14 days which I found complete unacceptable as they are quick to collect but taking their sweet time to refund! I demanded to speak to a manager and was put on hold for a very long time that I eventually hanged up the phone as I was on the call with them for almost half an hour. I phoned back and got the same agent where I demanded again to speak to a manager. After 5 minutes I was advised that the manager could not take my call as he is too busy!!! Really!! It now a week later and the only manager who bothered to contact me was the manager at the KFC we ordered, but seeing as this is a delivery issue with the app, this is now sort of my own problem. No feedback on my refund, no apologies for not getting our food and KFC letting us hang for the second time. Really pathetic service. Maybe writing a review on Hello Peter will get me some feedback when I can expect my refund for food never received.....
