Kfc burger uncooked with blood still in it

Kfc.. Phoenix plaza... I bought a zinger box meal and another 4 zinger wings today at 11am 20/07/19...The burger was not cooked properly and it blood still in it as for the zinger wings they were tasteless I called kfc and spoke to the manager and he asked me to come into the store. I told him I could only come in at 3 pm cause I was not in Phoenix at that time. When I did reach the store with the uneaten meal at 3 the manager was not there. I in turn spoke to another manager explaining what's wrong with my meal which I brought back. He saw that the burger was not cook properly and wanted to replace my meal but I insisted I wanted a refund because the food was tasteless uncooked and horrible... He was reluctant to refund me but I insisted... He then only wanted to refund me for the box meal and not for the other 4 zinger wings which my son ate cause he was hungry n we were on the road going somewhere.. I practically had to stand there and argue with the manager I front of other customers which was so embarrassing... When I started taking pictures and told him I'm going to put it on social media Then only he reluctantly refund my money... Kfc guarantee lol what a load of ****....
