Bad service

On 23 March 2022 at about 11h30 I placed an order(Romeo***)on kfc app and the delivery store was Suncoast kfc. About an hour later I called the store in order to locate my order. I was then told that they cannot find it on the system and I must contact ***. I waited for almost 10min after selecting delivery and had to cut the call and chose a different option. Customer care eventually put me through to delivery. I spoke to Makgton who was speaking softly and I couldn't hear her properly without telling to repeat even getting her name was a mission. I felt that she was being rude judging by her tone. She also promised to issue a voucher and I know that voucher will only come weeks later. This was my first online purchase where I had to pay on the app and she made sure that it was an unpleasant experience
