Is this a motability car? Is it your first car because usually old car lease is extended by dealership.
The thing is Jane many people are waiting for new cars because of pandemic ,shortage of staff, chips,parts,I ordered mercedes begining of June I’m ,kept in dark no information no approx UK delivery, car manufacturers blame pandemic & act like it’s not their fault genuilly don’t know anything don’t pass on any info. Dealerships are different but it seems you DS dealership is one to avoid.
My Experiance who ever you contact NOBODY KNOWS
