Terrible Accident in The Store and Nothing was done

Was walking through their store after work one night and was looking up at the signs to find a certain isle. I all of a sudden wiped out. The floor was wet. I called later and they said they had it on video. I was walking quite fast the impact of my body hitting that floor really took a toll on my shoulder,knee and hip. I had taken time off work and now have some long term problems. The managers said they forwarded the tape to head office and they played a game of cat and mouse with me until one day when i called they said:oh well its too late now, we can't do anything about it because too much time has passed. It's sad, I have 2 children and have to lie with this and they continue to make millions and did not offer any assistance of or compensation at all. Please keep this mind when you are shopping there.
