Damaged vapor line insulation in attic run of central AC

The installer of the insulated soft copper lines severely damaged the insulation on the central AC vapor line as it was dragged through the attic to set it in place.
These lines are 110' total.
Exposed copper is visible in a number of places and there are a zillion cuts all along the line, some of which allow your finger to touch the copper when pushed in.
Isn't this an unacceptable installation? Won't it result in condensation dripping onto my ceiling insulation, possible mold, increased operating cost, etc.
Shouldn't the entire run be re-insulated by cutting off the old and applying new slit insulation?

Can the slits be taped back closed ? Or are actual pieces missing.

Was the installation inspected? Supposed to be and it would fail.
