Assulted

I went to Fish and Chips Jean Crossing this afternoon to purchase food ,my order took longer than expected,I then requested a refund. After I just took my money from the counter then the lady who was assisting,got out then pushed me between the chair and the table and I got injured on my leg,hand neck and head. For the Manager or the owner just to come and offer me free food and nothing else. She said she will give the details of the lady so I can open a case and I am still waiting till now.
