Mahindra And Mahindra — Poor after sales service of mahindra xuv 500

Address:

560046

Car was given for 2nd free service at approx 9000+ kms.
The warrenty information & service book was given to be signed and stamped by the authorised service provider as proof that the vehicle was serviced as per warranty requirements.

The book was not stamped
Now after completing 10000 kms. I am getting a cautionary alarm "that service is due", because due to neglegance the software was not updated with the service date.

No body is answering calls of trying to help.
Very very poor and unprofessional service
