Review Dodgy rude cashier

Cashier didnt not ring up my oder gave me a slip tht belonged to a previous customer,took abt 6steps walking away from the shop and the pie fell onto the dirty floor noticed packaging is faulty picked up pie went back to show cashier the faulty packaging and got the rudest response of my life,highlighted tht she even gave wrong slip she then eventually rang up a steak and kidney pie and exchanged the pie,walked away again and noticed she put back the dirty pie in the glass oven.....went back and asked to see the manager only to realise the manager is the lady who had been standing next to her the entire time,i asked for HQ number and was given an empty pie packaging and told the number is at the back!!!!so disappointed i could even eat the pie (swapped) one .
