Policy Bazaar — hyundai is denying cashless because i have taken policy from policy bazaar

I met with an accident on 25th november and since that day my car is standing at hyundai service center and they are denying cashless facility saying since i have taken policy online they can't provide that facility to me and are asking 2-2.5 lakh rs.in advance.
What's the use of taking policy from your site if at the time of need facilities are denied to me.
