I'm splitting hairs here, but there are auto body shops with tow trucks that don't exclusively do roadside assistance and that aren't necessarily unethical.

But yeah, I worked in emergency road service for a very well-known insurer, and even the emergency road service providers are usually unethical assholes. Most were assholes on the phone, would nickel and dime everyone they could for anything they could (and some things they couldn't), wouldn't stick to their ETAs, would drop cars in wrong places, etc.

I still would trust those emergency road service companies over predatory towing companies like Siebert's Towing, or like whatever company it is that OP mentioned.
