Cross Roads — Cheating regarding car package

Address:

New Delhi, Delhi, 110020

I have taken cross road service but it's just awful. Executive came towards me and took 1500 Rs from me saying that it's a lifetime service for my car. But as per my conversation with customer care executive, it's just valid for 4 years. After completion of periods, they can charge the renewal amount. I had written multiple mails but to no output. Infact, they have stopped replying to the mails. Just a improper behaviour from their employees.
I want my money back. I can't afford to trust on people who are making false commitments in the initial stage only.
