NEW laptop going in for repairs after only 20 days without negligence from my side!

My boss bought me a BRAND NEW LAPTOP from Incredible Connection (Woodlands) on the 16th of June 2021. All seemed fine until a week ago. It started freezing, Office not responding etc. Every time I had to do a reboot loosing most of my information, although me saving my work every now and then. This being extremely frustrating, slow to start up and then I had to go back and see what information is missing - this not being time effective. So, to try and solve it from my side I backed up all my files and formatted the hard drive. The next day after setting it up again, I opened Outlook and Excel - still very slow and not responding. I opened up Task Manager and my CPU was fluctuating between 86% - 100%. I then went to Incredible Connection on the 9th of July 2021 and shared my problem. This for a new laptop is uncalled for. This should not be the case for a laptop being only used for a certain amount of days? As far as I'm concerned the laptop is under warranty, so they should either repair or replace the product. I preferred it being replaced (as I feel it is my right) as I can not afford being without a laptop due to my work load. According to them they can't replace it and had to send it back for repairs and I'll have to wait at least 21 days?? I'm extremely disappointed in their ethics and not meeting or understanding a clients predicament! I will definitely never support Incredible Connection in any way ever again.
