Raid Electric Liquid 90-Night Repeller Fails to Keep Mosquitoes Away

I am getting zero results from the Raid Electric Liquid All-Summer Protection 90-Night Economy Pack that I purchased four days ago from a Migros store in Datça, Muğla. I had previously used the same brand's liquid mosquito repeller and was satisfied, which is why I specifically chose Raid again, but this new pack fails to repel mosquitoes entirely.

I am using the product with the new heating device included in the package in a bedroom of approximately 9 square meters, leaving it plugged in continuously throughout the night. Despite this, mosquitoes continue to fly around the room and disturb us all night long. Comparing this to my previous positive experience, I suspect there is a defect with either the liquid refill or the heating device itself.

Suspecting a manufacturing defect, I request a replacement for this pack and an inspection of the product. I ask that the item be examined, that an explanation be provided to me, and that it be exchanged for a fully effective unit.
