Worse customer service ever received

I just been to Ackerman's in blue route mall and the service at the cash desk is disgusting the cashier (african girl pregnant not wearing a name badge )who assisted me was so deep in a conversation with the cashier next to her (Petra) who was also busy assisting a customer laughing out loud they were having their own little tea party while assisting us did not even care ,did not even greet or acknowledge me while she is ringing up my goods just went on with her conversation when I told her she shouldn't be having a conversation while busy with customers she just gave me one dirty look when she was done ringing off my stuff she just gave it without saying anything did not even thank me for shopping at the store nothing then the other cashier asked her what did she do ...so it's a norm they don't have any clue what customer service is this is the worse customer service a have ever experienced . Ackermans should invest in customer service training for their staff it's ridiculous.
