Problems with quarts top installation

[Kaiyu 0]

I have contractor to install quartz top on my kitchen cabinet. After installation there is a 4 to 5 mm gap between my kitchen sink and the quartz top. Is there any way to solve this problem? As for now, the big gap is ‘close’ using silicone glue and it’s look ugly. I worry the silicone glue would trap dirt and mold easily after sometime. I wonder what I can do to solve this problem.

Hi Kaiyu would you want to post a photo of what it currently looks like?

The gap is now filled with silicon glue. The gap is around 4 to 5 mm.

This is undermounted sink?

Yes it’s undermounted sink. The person who installed them claimed that the silicon glue will not shrink and trap dirt even though after many years. I wonder if water would come in contact with the kitchen cabinet in the future.

I think this workmanship is not acceptable. Please reject this job.
