Unexcceptable service

I have been fighting an unresolved battle since may 2022.I Bought a new HP laptop at telkom westage mall between March and April 2022. The laptop has been giving me problems since ever, I sent it to Pinnacle warranty several times myself due to the service that was not been rendered at the branch for me. Every time when the laptop comes back still the problems persists until l decided to take it to the manager at westage he send it again for repairs but the answer is still the same. The feedback was that the laptop has software issues and windows has to be downgraded which thru did from 11 to 10. What frastrates me the most is that the laptop it's within a warrant, used only few times now they tell me that l need to pay a fee for the software to be updated because it's not part of warranty. My question to them is how can you sell a faulty product to a customer, cleary this was not supposed to be sold to me. How can l purchase the product with software issues. As l speak l have been paying your debit order without any excuses maybe that's why no one cares about my complain. Can someone take my complain to consideration because am not happy at all and l believe they can be a solution to this problem if talkom value their customers. There is no willingness to help at all. Can l deal with someone else not the store manager because l have been doing that and there is no change. As l speak they have the laptop in store since l dropped it in January. The reason is because the software issue haven't been resolved so why should I collect something that is not useful to me.
