Jean Crossing Store - terrible service and dangerous entrance

I shopped at the Jean Crossing outlet in Centurion on Friday 6 November. It was just after 9am, and although I was 2nd in the checkout queue, I had to wait more than 10mins to be served. Only 1 cashier on duty, and no packers. Eventually the queue behind me had more than 10 customers waiting. When I approached the manager he basically fobbed me off as if it wasn't his problem. I was exceptionally irate as I left the store. I was pushing a basket trolley in some haste as I was now running late. At the exit to the store the rubber matting has broken away in parts leaving a gap between the rubber and paving. As I pushed the trolley the front wheels got stuck in this gap and with the momentum the whole trolley fell over, and so did I. I fell hard, and apart from the loss of dignity a lady experiences when falling in public, I also have rather substantial bruising to various parts of my body. Not a single employee came to assist me, however 2 customers did and rightly said that it was disgusting that the rubber had not been replaced and had caused me to fall the way that I did. I would appreciate some feedback in this regard please.
