Returns policy chaotic!

Bought a laptop in August 2021 which subsequently had issues with the screen blanking out. time I took the laptop in was in September. They contacted me after 14 days to say i can collect it as it was a software issue. The issue continued and I took the laptop in again in October. Got called to pick up the laptop again after 3 weeks as they said HP was getting the parts to repair the laptop. The issue still continued after collecting the laptop which i took back in December again and i got a call yesterday to say I can collect as HP has repaired the device. We have asked for a refund as we cannot keep taking time to go into the store to collect a laptop that invariably does not work. We also had to purchase another laptop as the reason we bought the laptop in the first place was because it was needed.
