Terrible service regarding warranty for Samsung Galaxy Z Flip 5

I am writing to express my frustration and disappointment with Samsung and Takealot regarding my Samsung Galaxy Z Flip 5. Despite the phone still being under warranty (I've had it since November), my claim was rejected and claimed as warranty voided. I noticed a green line along the fold of the screen, which was concerning but as I was working I simply closed the phone to continue with my work but when I checked a few minutes later the entire folding area had turned completely black and was no longer registering any touches.

I immediately started doing research and found that these problems are well-documented as common defects in the Galaxy Z Flip series.

I scheduled a refund with Takealot to which they said they would be sending it to be reviewed by their merchant. It's taken 4 weeks already and they finally reached out to me today only to say the service centre refused to honor the warranty, claiming it was due to "impact damage." This cannot be true, as there is no external damage to the phone (I always kept it in a cover and it had never fallen or gotten knocked either), and the issues clearly stem from manufacturing flaws regarding the hinge mechanism.

They even had the nerve to quote me R13k for a REPAIR for a phone that only cost me R11k brand new when I bought it.

This feels like an attempt to avoid responsibility for a known defect in their product.

I am extremely disappointed and upset with this service.

I hope this matter will be resolved promptly and fairly. Otherwise, I will have no choice but to escalate my complaint further.
