Renault Captur and the Starter – an infinite story ????

What do you need to know about this? We have a Renault Captur EZ 11/2013. About Christmas we were on the road for a few days with our Womo and after our return we wanted to go shopping with the Captur. Didn’t jump on. That was on 5.1.2015. Call in the workshop, which meant first: Certainly the battery!! So charger hung up and the battery fully charged. Tuesday – with us holiday – tried again, it still didn’t. So Wednesday in the workshop called and they got him. After we then in the afternoon called, it was: The starter is defective. Then for quite a long time nothing happened until we asked for a workshop replacement car. Mobility guarantee from Renault. That was then already a problem, because they have just registered a Clio fresh, but with summer tires. Well, if we have an accident then u.U., we can not bear a share? because of the tires ?? So then again I have to call the Renault customer service in Brühl and ask for help. Then we have now the car – with winter tires. Our car is so since 7.1. 2015 can not be taken from the workshop? Do not deliver something?
