Impound lot

I have a question. I am in a very bad financial bind, and my vehicle was towed to the impound lot last Tuesday. I paid my tickets Friday thinking I’d be able to pick the vehicle up, not knowing that they’re closed due to Good Friday, and closed for the weekend. Paying the extra storage fees for the additional days is going to be hard. Do the impound lot let you negotiate that amount or set up a payment plan?
