Laptop problem

I bought a HP laptop on the 16th of November 2019 at Dion Nelspruit which is now closed down and their ledger has been transferred to Game, in April 2020 the hinges of the laptop went loose. But unfortunately I lost the receipt. I went to game and I was told that at least I must get a bank statement, which I did. I went back to Game with a bank statement, they didn't take the laptop on that day because they said their system is being upgraded, they told me to keep on calling to verify if the system is finished with the upgrade, which did. I went back again and they told me that a senior administrator had to request reprint from their head office as I didn't have a receipt. I went back again to found out if the recept has been requested. They took the laptop for repair, after 3 weeks I made a follow up, they told me that the laptop has not yet been collected because of Covad 19, on the 28 of July they called me and told me that the people from repair wants an original receipt which I don't have. Please help me.
