Help With Unauthorized Car Repair

[non_engineer]

I noticed there have been previous threads with a similar subject. I was hoping to get insight from those of you who have experienced the same.

My vehicle broke down. It was brought into a local garage for a diagnosis. From the diagnosis, a detailed work order with costs was supposed to be provided to the me to review and consent to. No documentation was provided.

Instead, the garage started repairs by removing the engine head. The engine head was sent to a subcontractor to repair. The subcontractor notified the garage of the repair cost. The garage authorized the subcontractor repair without informing me.

After the subcontractor repair already commenced, the garage contacted me by phone indicating the cost of repair, and requesting a deposit to commence the repair. The garage did not indicate the repair had started.

The proposal was rejected, and a tow was arranged. The garage refused to release the vehicle - claiming repairs had already started. They held the vehicle ransom - citing a Garage Keepers Lien. However, they gained possession of the vehicle using Unfair Trade Practices. They did not produce any written work order. They did not obtain my consent for the repairs.

Even their webpage states they produce a detailed work order before starting repairs.

They have possessed the vehicle for MONTHS now.

Thanks in advance for your insights.
