Poor service, ruined my item – Dolly: Moving & Delivery Help Review

I booked a dolly to move a quartz bathroom vanity in November . I purchased the optional insurance in the amount of $1000 , since the value of the countertop was about $2500. Movers arrived and one of them proceeded to maneuver the piece and it broke and shattered. He immediately called it in to Dolly and we took pictures etc. Customer service called me and I sent them all the required documentation, including pictures of the item before and after the damage and a quote from the store where the item was originally purchased at for replacing the item. They are refusing to pay me for the insurance I purchased, offering to just refund me for the cost of the move. I’ve called numerous times, and spoken to Jeff McMahon, their customer service supervisor and he has refused to escalate my claim and answer my question of why they offer additional insurance for purchase and then will not put me in touch with the insurance company they supposedly use. This company is not reputable.
