Typo in Schengen Visa

My passport was stamped with Schengen visa on 24th April and is valid till Oct with stay of 90 days.

I received it via courier today. I live in Bangalore and due to appointment date problem, visa was stamped from Mumbai Consulate.

There is a problem in my Visa . There is a typo in Passport number printed in stamped visa .

The first letter is written as M instead of K. All the numbers are correct .

Mxxxxxx instead of Kxxxxxx.

My flight is booked for 30th April and I am arriving there on 1st May. I have only two working days before travel.

Please assist me - what should I do?

This travel also can't be avoided as it is a corporate travel and it's quite important due to certain Project Responsibilities and Client Commitment.
