Im very hurt and dissapointed by their service

I went shopping with kids and my sister inlaw,i wanted to buy some clothes for kids and asked where is kids area was advised by staff member to use the escalator inside the store,within blink of eye my sister inlaw and kids where rolling on escalator up and down until one person stopped it,we were taken upstairs for first aid and check i guess They called a manager i dont know his name because he never bothered to great,or introduce himself he acted as if is our fault Never bothered to care how many people injured or how big was the injury all he said was if they call ambulance ill be liable for charges and i must make decision he then left Im very hurt and dissappinted i went to Edgars for clothes not to get people injured Im not a doctor how am i supposed to know wether ambulance is needed or not What is their responsibility as store because i was inside the shop try to buy The only thing i heard from them is why i didnt use lift instead of escalators and next time i must use lift and that escalator are very fast another lady was injured two days before our incident by that i felt they dont care and trying to justify issue that my kids and sister was injured inside their store I regret ever going to edgars and i will never again
