Appalling customer service in the Cavendish branch

I walked in Pic n pay cavendish to grab a few items this morning...when I get to the till points...a cashier by the name of Mayamane (as per the till slip) points out that the can of energy drink that I took from the fridge is squashed, I thank him for pointing that out...he proceeds to say I can take another can...which is all good and well coz that's how I got it from the fridge to begin with....but now he is asking me to GO BACK TO THE FRIDGE to replace a defective can that was not even meant to be packed there...so I ask him why I as a customer must be the one who goes all the way back to the fridge meanwhile there are how many pic n pay employees walking the floor who can go and get the can for me.

He starts arguing and asking if its his fault that the can is squashed....I ask if it's mine, he says well its your can...So I tell him its pic n pay's can and to stop the hassle ciz my time is being wasted, he can void it and ill have a word with the manager....it is only at that point that he askes the till packer who had been standing there doing nothing to go and fetch the can from the fridge...now I ask him what was so difficult about that?...he then says I came to their shop looking for a fight...SO ME AS A PAYING CUSTOMER...CAME TO A GROCERY STORE TO PICK Q FIGHT?????...I have been a customer at pic n pay Cavendish for 3 years of me working in Claremont...never have I had such bad service, I WANT HIM to explain to me how they are trained and I AM entitled to an APOLOGY...from HIM
