KFC Phoenix

On 3rd January 2016, I purchased one piece meal with mash & gravy from the drive thru in Phoenix. I took the package and left it on the front passenger seat because it was too hot to feed my baby. When I reached home I lifted the package to take it out and surprisingly the bag broke and the hot gravy fell all over the seat and the hand break compartment where my cell phone was. I was upset and I went back to the store because this was the 2nd time in 2 weeks that this has happened. The store manager (Kevin) came to the car to have a look. He apologized and then he asked an assistant to clean up the mess. I also told him that if my cell phone is damaged then I will hold kfc responsible. He replaced the meal, and when I reached home, I had a look at the meal and it was dry and terrible. I also found that my cell phone was damaged. I called him and explained him, he then asked his area manager (Pradeep) to call me. Pradeep was of no help at all, so I called the hotline and related the problem to them, They promised to come back to me, but a few days later I received a message on my cell wife's cell that the case was closed. My repairs on the phone by Samsung cost me R1800.00 . help
