********** treatment of customer

I've written my complaint on your website on 7 March 2018 and have received just no feedback... I received a rain cheque from your Willowbridge shop last week. I went to Tygervalley on 7 March and bought the Omo washing powder with the rain cheque. The supervisor (Wendy Kilo) queried but still approved the transaction. She then came back and physically removed the items out of my trolley and said she can't allow the purchase as the rain cheque was not signed or dated! This after I have already paid for the goods and it was my property!! She then grabbed the till slip from my hand. This was ******** to say the least. The manager, Chris M agreed with his supervisor and told me I need to return the items and go to Willowbridge. No where on the rain cheque does it state I need to go back to the store which issued the rain cheque. I explained that it is not my problem as I am a customer and don't know the protocol of completing a rain cheque. I then returned the whole trolley of R800 goods. I've never been so humiliated in my entire life. I have done absolutely nothing wrong as a customer and yet these people treated me as if I was a *****. They couldn't even refund the goods to my card and gave me cash. This is so unacceptable Pick n Pay as I am a very loyal customer who is deeply hurt and humiliated by this experience! I am hopeful that PNP management will treat this incident on a serious note and deal with it appropriately.
