After service scirroco R coming with problems

Last week Monday, booked the car for service.<br> Car before service was excellent as you can imagine driving a VW Scirocco R type. Since the car had to go for its second service at 30 000kms, all went well except day after service car malfunctions electronically. No more first kick starts, needed to at least try twice before it starts. This ****ed my day since you can imagine before service the car had no issues whats so ever.. morning after that day, I tried to unlock the car and windows did roll down a bit as its normal function, and had to force open the door. Call the VW Service guys to complain about my problem which was 2 days after service and was told that I should bring my car next week Tuesday so, and had to fight them so hard for them and literally had to drive there. How can you tell me that i should bring my car a week after while when i booked it it was immediate and this **** was made by them, since it came to them perfect. It finally was taken in for \test"and was told that the car that only gone for 2nd service battery cell is dead"
