KFC not providing me with service after I paid for my order

About a month ago I purchased a meal on the app, the food never arrived. Then I called KFC and they provided me with a voucher. I used the voucher to purchase a meal on the app again from the same store, the store cancelled the order and the food never arrived again. The voucher I used is no longer valid as it was used in a cancelled order. I have called KFC multiple times, each time they notified me that they will be calling me back. It's been a month and still no call backs. I called them again this morning and the issue is still unresolved. Case Number 725058. So they took my money a month ago, provided me with no food and the case is still not resolved, this sounds very much like theft to me.

So thus far,I have received no calls from KFC, it's me hjaving to constantly call them, I have probably spent more money in air time calling them, than the actual cost of the meal!. Poor service
