Hyundai Motor India — Sharing customers private contact to third parties

I recently purchased a car from Hyundai Motors. I've been recieving scam calls since from "holiday companies". First I got a call from one "Caribbean Holiday International" and now I got a call from a company that apparently is tied up with Mahindra. It is just pathetic that Hyundai Motors shares it's customer data to these third party scamsters. I hope they check their company for data leaks or are held accountable for these confidential data leaks.
