New Manufactured Quartz worktops - pin holes. Epoxy repair or replace?

[Colink]

A family member has had new manufactured quartz worktops installed 1 month ago.

 

Worktop now has about 8 pinholes some the size of a pin head). See image and short video attached

 

Is this to be expected and is an epoxy repair an acceptable solution or should they be demanding a new worktop?

I know what I would be doing and it doesn't involve a repair of any kind. If the installer/manufacturer insists let them do it on the proviso that they fully understand that if the repairs are not satisfactory then a replacement will be installed instead.

A repair will be invisible 

May be a stretch to get a new worktop
