Samsung A32 cracked screen within 1 week (not dropped)

Hi, I have laid a complaint with Samsung over 3 weeks ago. I am getting no joy. I got a Samsung A32 4g on a Vodacom contract. Within in one week of having the phone a hairline crack started on the lower left side of the screen and it has progressively gotten bigger over time. I reported the situation within 7 days of receiving the phone but was told to take it to a service center to be repaired. This is unacceptable as I did not drop the phone.

I still have a Samsung J5 from probably 8 years ago that I use as a wifi hotspot. The phone has never had a screen protector and I carry it around with me everywhere. The screen is still perfectly fine. This brand new phone which I had less than a week develops a crack after a week and it has not been dropped.

Please could someone reply to me urgently.

Thanks
