Teljoy - Faulty laptop

I have an active contract with teljoy since 1st September 2023. The contract is for JBL music box and Packard Bell laptop. I have no problems with JBL but since the start of the contract had the laptop up and working for 2 hours. Since then it has been in for repairs. It was repaired the first time days after I received the laptop and came back to me after a month with the same problem. It is at the moment again in for repairs and has been there now for a month with no feedback. I have no guarantee that I will just receive a laptop again which will be in working condition. I would rather just keep the music box amd cancel the contract in regards with the laptop and Teljoy reimbursing me for paying for a laptop (which I needed desperately at the time) for 4months and not having it at all.
