Unhelpful and rude attendant and my unresolved issue

I was so disappointed when I went to Pep stores Pinetown and the disgusting customer service I received from a lady named Fikile. I bought items and R160 airtime on Monday 27th January 2020. I lost my RECEIPT so autimatically I also lost the airtime because it was attached to the RECEIPT. I went back to the store on January 28th 2020 with all my items which I had purchased the previous day and explained my situation to a rude lady named Fikile. I then requested they print out my receipt from the Previous day so I could contact my cellphone service provider for them to retrieve my airtime and she said she couldn't do so since I wasn't the only Customer and she has to print out all of the previous days work. I even showed her time of purchase since I had swiped my standard bank card. I need my airtime back or at least my RECEIPT so I can follow up with my service provider. R160 airtime is not a small airtime.....
