Bad service Pick n Pay Customer Care

I had a rather unpleasant experience dealing with an agent from pick n pay customer care. I lost my slip and needed to return a dress. The supervisor was very nice and helpful, she called the customer care so they can trace the slip using my smart shopper. Unfortunately on the other end, the lady that took the call was the opposite. The supervisor at the store kept telling her to look for a clothing item on the slip and she kept insisting that she cannot see it. Eventually she gave me the phone, i kept telling the agent the same thing and like she did with the store supervisor she kept saying to me there is not dress/clothing purchase on my transactions. Fortunately i did not give up, eventually she goes through the items line by line, and guess what, the last item says Bodycon R90, then she says is that it. No apologies from her, no acknowledgement of wasting my time. What annoyed me was her insistence on the fact that the purchase is not there, even though i kept on telling her it's impossible, it has to be there. Unfortunately i did not get her name
