Zoomcar — Account is under black list

I am a regular customer of Zoom Car but from a couple of months, i am trying to book a zoom car but the application is showing that you are blacklisted by the zoom car without any reason and intimation.

After that i have emailed almost 3-4 times to the zoom car support but there is no response from there side. I have also called so many times to the customer care number but not able to connect with the representative.
