Matrix Warehouse Computers Springfield refuse to refund me and insist that the old product they sold me this year March 2019 is not theirs, a bunch of ******!

I am a customer for many years at Matrix Warehouse Computers based in Springfield. This year in March 2019, I had purchased a Kapersky Anti Virus from Dillion and loaded it onto my one device my laptop. My laptop crashed, my hard disk was replaced and I attempted to reload Kaspersky but I could not. I contacted Kaspersky direct and they had informed me that Matrix is a third party supplier and I need to approach them for a refund. I just went to Matrix Springfield now explaining my situation and they wanted to charge me to check, this was a black gentleman that was in the technical department that stood on the floor, I refused to be charged for something that is not my problem, then they said they would check free of charge. I am a I.T. user graduate and I am well aware of how to handle a laptop with care and to keep my software organized. I showed them the product and my slip, they refused to accept that this was there product yet this was the product they sold to me in March 2019. I spoke to a white gentleman in the technical department who asked me why did I not list my device and licence on kaspersky, I was not told to do so. He also told me this can't be there product as it is very old. They still said no we will help you but denying that this is not their product, he just frustrated me more. They made me look like I am *********** and that I am a dishonest person. They were doing all this just to avoid refunding me. I have never been so applauded in my entire life, they are ****** and making me look as if their product not working was my fault. He made it look that maybe I had put this licence on many devices when I just have one laptop. I still had 200 activation days when my hard disk crashed. I don't think it is my issue if the product did not reload and if they were *********** enough to sell me an old product, I told him he needs to train his sales staff to sell the correct product to customers and not make that my problem. All I wanted was a refund! I am totally disgusted with Matrix Springfield, they are all ****** and not trustworthy! I am going to tell all my friends and even inform the media not to go to Matrix Springfield. I did not want to speak to them further I was very angry and left as they still insist their old product they sold to me is not theirs. As far as I am concerned they are all ****** with no manners and no customer care s****s at Matrix Springfield, you need to get new honest staff there please who will sell will not sell old products to customers. All I want is a refund for an old product they sold to me!
