Dollar General

I live in St. Matthews, South Carolina. The Dollar General is located in a 1950' era grocery store. The roof leaks after each rain storm. I went into the store at about 5:30 p.m. on 7/8/20. I was looking for toilet cleaner and sympathy cards. The store was partially flooded. There was yellow tape on some of the isles, but not the one I went down. My left foot slipped and twisted my ankle and knee. I did not fall, however, the ankle was very tender and swollen for 3 days. The "Manager" took my name and number. I have not been contacted and need medical attention for my ankle and knee. I called Dollar General Customer Service and was on hold for 45 minutes before being disconnected. Please advise.
