Terrible Treatment by manager and fellow cashier

I was at Pep Home today at precisely 17:20 checking out the items I bought, only to be told that I the items are priced for tomorrow, with so much attitude by the cashier who didn't even have a name tag on. I requested for a manager as she kept patronising me in public, the manager was no different either. I am appalled by this treatment, I was made to be a laughing stock and they showed no care whatsoever.
