Disgusted and disappointed by service

I had their buffet and ask three staff members if the meat***** were purely beef. The lady serving the food assured me that it was purely beef! My waiter assured me that it was purely beef and another waiter assured me it was pure beef! i<br> I ate the meat***** thinking it was pure beef! When I got home my stomach felt very unsettled and throughout that evening I had a bad tummy! This lead be back to the store the next day Sunday just to make 100% sure as I had a very unsettled tummy the manager on duty also assured me that it was pure beef ,putting my mind a bit a ease then she brought out the packaging out revealing it was it was a mixture of pork and beef! I was horrified and disgusted feeling even more ill as I am a Muslim that has just completed a month of fasting! I was ensured that someone higher would call me latest by the Monday it is Thursday and no senior manager has called me! I don't know if I feel more disgusted or disappointed that nobody cared to call me back after this dramatic experience!
