Bad experience pick n pay (Bradley Peterson's store)

Dear PnP Customer service Team.

I would like to write and complain about a horrible service received to day at one of your branches Cavendish square in Capetown. I went there seeking a correction of my previous day purchase made in Somerset branch. Got there to a lady who did not want to check my receipt nor listen to me, she just wanted to call a manager. A manager named Bradley Peterson came with the most arrogance and a very bad attitude, he did not look at slip he was holding and was just ready to dismiss me referring me to Somerset branch, i asked to point out to me a policy that is stating that he can not assist me at his store, he referred me to customer care and asked him to connect me to customer care and he said he will not do that. He was calling security on me for seeking clarification and pointed me to other customers who were waiting for me. I am not happy how Bradley and his staff are treating customers especially of my color. Hurt as I was, went to Claremont branch because i still needed to buy two things i forgot the previous day, i got assisted there very nicely, they checked my slip and pointed out the error and were willing to assist me and corrected the error.

So i have few questions, where is policy was Bradley and his staff quoting from, is this how pick n pay trained him to be, look at our appearance and decide if we worth his time, is Cavendish privately owned by Bradley Peterson and not using same policy as the other stores?

I hope to get your response. Thank you.
