Capital Stereo Stereo speaker purchase. Destroyed, damaged, partially restored installment in car. Fremont California

Purchased a $125 full speaker installation package for my classic car.

They installed the speakers much to the damage of the car. Door panels are loose, driver's door arm rest and electronic controls are loose. They did not rescrew/bolt down the back brake light in the rear dash. They literally broke the ends of the back seat, even to the reefing on the seat damaging and loosening it for the back seat, and then reefing on the seat back so that the whole back seat is damaged and loose.

Better Business Bureau has given up the case as closed and unanswered by the manager of the business.

I have personally gone back, very polite to see if they would honestly repair and restore what they have damaged. They have been verbally abusive to me and about the car.

My car agent being of the same Mideastern persuasion and religion tried to assist without avail.

I need this company to properly repair, or have others (please!) do a full repair of the entire parts that were damaged, and to even consider replacing the back seat that is now broken and loose.

People don't treat people like this.
