Debonairs, poor service

I am extremely disappointed in Debonairs, I used to be a regular customer. I recently used the app to order and when I got to the store to collect they hadn't even bothered to check their system to make the pizza, I chose not to wait for the pizza, I got home and placed another order on the app(this time for delivery) I paid online, the transaction was successful and they did not deliver the pizza . I chatted to one of the consultants on the app who was completely clueless and could not help me. I tried calling the store and customer help line with no avail. the app later updated and stated that that specific store had gone offline. they had no proof of my order and the app had also lost all previous orders. it was not a large amount which is why I didn't bother too much for the cash , but I will not be using the Debonairs app or the store ever again , its too much off effort and really is not worth it.
