Game Mamelodi assistant was very rude

I went to game store mams Mall to ask them for my phone recipient. Which I lost to take my phone for repairs at Samsung. And my phone had already being opened a job card at Samsung they just waiting for the receipt. The rude lady said to me it's not possible for me to get an receipt, she said I must remember the exact date I purchased my phone. I told her I don't and even if wanted to remember it was impossible. With alot we going through I told her I have my ID and phone Imei but she was not willing to assist me. She did not even bother to stand up where she was sitting to try and check the phone file or ask what year was the phone bought. I can just say she was not willing to assist me. As she even told me that she doesn't expect me to hast lost my contract I must be having. By saying that to she means that she doesn't want to be bothered with looking for lost receipts 😔
