Uber Account Blocked. Pls help

Today out of blue Uber blocked my account and I received a call from their safety team saying that a recent rider has informed that it was someone else other than me who completed the ride. They asked me if I have shared my login with someone else.
It is a 100% false claim and I don’t know why would someone make such a complaint? If they had doubts they could simply ask me for further clarification.

Uber has now asked me to send my latest photo for further investigation.
My question

Has anyone had similar experience?
Will my account be reinstated? How long does it take?
What other options can I explore if Uber decides not to activate my account.
