Food poisoning KFC Market Square Wellington

I recently bought KFC in wellington market square and ordered it online.

After receiving my order it was shared between myself and my 3 colleagues. Two of us ate only the chicken and chips and one ate from the zinger wings. About an hour after we ate we all started running to the loo like crazy and had an extremely horrible experience. Our stomachs are still aching and after we called customer care the lady was so rude and hung up. We then proceeded to call the shop where we had ordered from t=and the manager advised that that is what happens when you eat zingers wings. This is not our first time eating zinger wings and one should not run to the loo after an hour after eating it. I mean if all 3 people have the same experience an hour after consuming some of the food why would the manager feel the need to tell us we must see how we feel during the day. Management in wellington is horrible and inconsiderate.
