Maruti Suzuki India — Service was poor

I would like to notice you that at the time of delivery of my car I noticed that my pendrive was missing from my car and the fuel meter reading was blinking with low level . There were 4 blocks of fuel meter reading at the time when i gave for service.Only 4 km test drive was done.I lost my pendrive. I didnt expect this type of service. I am unsatisfied.
