Worst customer service experience ever

Today I was at the Ackermans store in Southgate to pay some bills. While paying for my avon account the pos device froze and I was moved to another till. While paying my dstv account the cashier I was standing by asked her colleague Nikiwe Ngidi who just came back from a break to assist my husbad in paying the avon account as her pos device froze when we tried paying. Nikiwe with no regard for customer service whatsoever started questioning her colleague in Zulu as to why she should allow my husband to pay by her as im already being assisted by anothet cashier and that he can wait for me to finish and pay once im done. I asked her why she is being rude and not assisting she just gave me a blank stare as she was surprised that I understood what she was saying.

Im put off by this ladys attitude as thats not how you behave in a customer service environment. She didnt apologise for once I confronted and continued ignoring me.

On top of this service received I was told that my rewards card no longer works and they cant give me an explanation as to what has happened to the rewards I've accumulated thus far.

You have lost a possible client as I was going to open a Ackermans account.
