Poor service

We had extremely bad service, we went to the KFC at Zambesi Junction, we could not place our order because the systems were offline so we had to wait in the drive-thru for nearly half an hour because there were cars infront of us, the person infront of us claimed her money back due to bad attitude and bad service, after that we went to Kollenade KFC where the service was just as bad, again we have waited about 20 min and again the person infront of us gave back his food and claimed his money back due to poor service and bad quality of food, after receiving our food I can relate to the guy infront us' behaviour due to the fact that we also received bad quality food, clearly the buns of the burgers were old and over expiry date, it was very hard. We see this as a ugent matter, we are regular clients but it is not the fisrt time we experience bad service and it is from both KFCs. I hope you find the above in order, we await you urgent responed
