Average costs for a tow truck and storage?

Hello together. I hope I met the right area in the forum. Otherwise it had nowhere really fit in. I would like to know how high the towing costs in average so are after an accident. My car was towed about a month ago after an accident and since then stands at the tow truck on the yard and is to be picked up on Monday. Before I should pay the still open invoice. On the phone they told me first what from 500 to 600 € and then 10 minute n later they called me and said that they had just looked and I should bring 1000€ with me. On my tow tow towing after accident zone 1 was checked. In addition, rescue 45 min. And under the job is Bergen behind the guard plank With weight surcharge and that has not been made. Was also only a dare of the golf class. So simple car. In the office also a price table hung but unfortunately I did not remember it completely. allow to tow costs from 155€ and under storage I think there was 10€. But I can’t tell you exactly. Maybe another small night surcharge because it was around 6am. Maybe someone knows about the prices of towpers and can tell me how the prices are about? If there are large regional differences the use and storage location is in NRW.
