Family Dollar complaint: Customer service lacking

My husband and I went to this store because most of the time it has what we need on entering I was greeted by Tay she was counting I guess what is cash even though I never said anything to her (speaking to my husband) after we were done shopping Tay told us to put the things on the counter because sometimes we are done shopping and when we ready to ring the bell we told her we are ready she completed the Cashing I put my card into the machine, then realized that I had entered the wrong card. I pulled out the card and replace it with another card. Tay had stepped away from the register I called her back to tell her I’m have replaced the card and she yelled. Oh, she cancel her transaction and the machine went down. her appearance seem to be off mad rather, and Regina came and said to her relax, breathe and start praying holding her hand to Tay head praying I removing the bad energy she brought in here my husband left because he had something to do so I had waited in the store until the machine came back up then Regina keep making rude comments about me breaking the machine and saying to customers. Oh look how many customers we are losing Tay walking back and forth looking at me and making comments about stealing I have shopped with family dollars over the years and I’ve never gone in one of the stores and taken as much as a Sweet I felt so disrespectful today I have decided not to shop at family dollars and if this is the level that your customer service has gone to I would never recommend anyone to shop there
