Frustrated injured customer

Monda I was injured inside the store toilet, before I even could purchase my meal.. And had to be rushed to the emergency room, where I was told my finger almost got cut of.. Had to go to theater and stitched.. When I call the company to tell them about my experience they told me they can't do anything for me.. Yet I now have to attend doctors because my finger won't work again.. It is now a disability.. I'm extremely frustrated and would like to be assisted..
