Complaint about Boxer Mount Ayliff

I am very disappointed with the treatment I received from the manager of Boxer Mount Ayliff Eastern Cape...I bought a stove on Sunday 03/09/2023 and the stove did not work... unfortunately I lost the slip but I believe they can do reprint because I used my bank card so I have a bank notification message which is the proof that I really bought it there....I went to boxer on Monday and I asked the staff to call the menager and she said she will not bother by calling the manager because she will not help...I left the store ononday without being help,today Tuesday I went there and I was attended by the store manager who was very cheeky,she was not even looking at me by the time I was explaining my problem....I am very very hurt because it means I lost my money
