Very bad service

I recently relocated to Mmabatho so I went to pnp to get some few groceries then I went to the tills to pay, as she was scanning my groceries I left some groceries and the cashier was so rude to me she told me I must take back things I wasn't taking back to the shelf,I ask her if did you ask other customers to take back their stuff coz they were groceries on her counter that were left by other customers.she just looked at me and gave me attitude.then today I went to buy groceries I forgot my bank card at home so I did cash send for 300 then I went to the cashier to pay for my groceries ,she told me she doesn't have cash so I can't buy what I wanted.i left without buying anything. I am so disappointed with the service that I got from them I doubt I will shop in that store ever they don't value my money
