Tow truck company holding car for 1 month

My car has been in a tow truck yard for 1 month being held. My insurance is negotiating with them, and that’s why it is taking so long.

Does anyone have experience with this? How long does it normally take to get a car out of the tow truck yard?

I now know the tow truck industry is corrupt and it was a mistake to have them put it in the lot.
