Insufficient Funds status in online and Date of birth is wrong in receipt

My h1 was picked in lottery but my status as " Payment Fee Was Returned For Insufficient Funds " and the DOB is wrong in the receipt which i received from my employer. How serious is these issues ?

Employer can fix the fee issue by funding their account and letting USCIS know about it.

As for DOB, ask employer if they filed it correctly in I-129 or not. If they entered it correctly, then they should ask USCIS to fix the data entry error at their end.
