Disappointed client needs REFUND NOT CREDIT NOTE

I purchased a Packard Bell laptop in November 2022 and only started using it Mid January 2023. I found the sound was terrible and had to use my earphones on Skype calls , I also found the laptop heats up in no time. I returned it to the IC Newmarket Mall and John stated the technician was not in to see to it. I was told I will be given a credit note to fix. I know it should be Packard Bell that should see to it as IC technician opening the laptop the warranty will be void. I told them I want a refund but they refuse. I am really ticked off as I emailed and phone IC customer service but I was told the laptop is getting fixed in store and I must call the store yet I got a SMS that the laptop was given in for service with a job card number. IC-PACK-***. I DONT WANT THE LAPTOP OR ANYTHING ELSE FROM IC AS THEIR SERVICE SUCKS. A FRIEND IS HAVING THE SAME ISSUE FROM IC. I JUST WANT MY MONEY BACK PLEASE
