Family Dollar complaint: extremely unprofessional store clerk and manager

I went in between 12 and left before 1. They have those carts you cannot take out of store so I had my son in wheelchair so I l9ad3d my son up and locked car because I had to run cart in (my sin in wheelchair) before I went inI noticed I could not find my keys but I already locked the door. My son does not know how to unlock. I went into store told them what happened and asked if they saw my keys if I cam please be contacted. My husband left work to drop me off spare set. The employee was extremely rude and says I cannot hel0. I am busy stocking. She could of told me I syead I will get manager for you. sh3 was extremely rude and I did not know if she was not manager. I looked around store really quick (my son on care because ypu got to take cart back inside and my son’s in wheelchair and there is a little hill to get I. the store.
So the manager took my number and name and I explained how she was rude he snapped right back at me. she was busy shecpyld not help ypu. ypu should have asked for manager and extremely rude. I had no clue at time manager was. I still have not dpund my keys. I hope do not throw my keys because I said on my way put I am calling cooperate because I was treated extremely bad.
