ADAC/Private leasing ZOE

Hello everybody, I’ve been trying to get a private lease for a Renault ZOE for a few days. However, I just get a cancellation from every dealer (PLZ 7x). Two told me that they were “no longer instructed to offer private leasing in the short term”. How can that be? The ADAC is still advertising, but I can’t perceive the offer anywhere… Have they already reached the CO2 targets for 2020 or do you know more specific backgrounds?
