Uber India — not able to access account

Address:

Mumbai City, Maharashtra, 400019

Customer care not understanding the problem. Am emailing them since last 10 days.

I don't recall the password of my account which has my cell no as my user id and also
I don't recall the email associated with the cell no.

To revive my password they want an registered email associated with my cell no.

What i cant recall how to give the customer care?

Now how to use uber using my cell no.?
