[Resolved]  Mahindra And Mahindra — unethical behavior

I bought a mahindra vehicle (Xuv500) about 6 years ago from india garage dealer in bangalore. But, my phone number and vehicle details have been furnished to all the new and old dealers in bangalore. So, overtime my vehicle is due for service, i get so many pesky calls from everyone for getting my vehicle service. They do not even stop if i ask them to remove my number from their database. What do i do? Change my phone number???

My personal information has been distributed without my approval for this.

This is extremely disturbing as to how confidential information is managed in mahindra : (

Please take corrective action if possible.
