How would you behave?

Hello, again my grandma is on strike. Last night gg. 20:00 o’clock Grandma parked in front of the house. This morning at 09:00 o’clock it should go to football with the son. But nothing there . . . . that attracts thanks to a new battery which I did with in January, but fully through does not start. But now the glou : and again the petrol pump is broken. And although I stopped last year on 29.04.11 in Berlin, the pump could not be installed on site rep. therefore at the ADAC. K napp 8 weeks later (25.06.11 ) the grandma stays on the highway again, petrol pump in the rear again, off to Opel Peschel in Dresden. By chance the workshop has the same spare part supplier as in Berlin the ADAC. So they exchange them free of charge. What should I do now, a loud one at Peschel, or is there still a guarantee or something on it. What would you do? How would you behave? Thank you for help.
