ILL MANNERED CASHIER

Checkers Greenvalley 2019/10/29- between 18:30-18:45 - My mum and I went to the express till and after paying for our goodies I asked the teller if I may have one of their new cards and I didnt get a reply, thinking she didnt hear me i obviously ask again "can I also have one of these cards?" So the cashier gives me the card (without saying anything) so i said to her "so what should I do now?" and she still ignores me, furious i give her the card back and ask for her manager and she still decided to ignore me, i get to the managers and explain that one of their staff members are extremely rude and is flat on ignoring me when asked about the card, so he rep**** "sorry about that I will sort her out" so i ask him what will be done because what if when I leave nothing is done and she isnt reprimanded, he assured me that he will sort her out as he doesnt know her name because he is still new to the store, and proceeded to assist me with the card, whilst assisting me the cashier starts complaining to the customers that were behind us, (mind you she had nothing to say when I was talking to her but definitely had a fat lot to say about me to the other customers, I was surprised that she could actually speak) I did ensure that the manager again knew that I was not impressed after having shopping there since they've opened that I have NEVER received such bad customer service, let alone experience such an ILL MANNERED and RUDE staff member as the cashiers are usually helpful and friendly. I really hope this cashier is taught some people s****s as her behaviour today was completely and utterly DISGUSTING & DISRESPECTFUL and I hope she never treats another customer like that again.
