Dear Sir,

In the financial year 2019-20, One service provider have provided service bills to the different service recipient and that bills have not been shown to the GSTR1. Not only that the bills which have been shown in GSTR1 not given to the parties. i.e. bills lying at service recipient (they take ITC on the basis of documents) not shown in GSTR1 by service provider and bills, which shown in GSTR1 not provided to the service recipient. 100% mismatch. 

Further, Service recipient has paid TDS (194C) on the basis of documents time to time and submitted TDS return. which result reflected in 26AS. 

Plz suggest me how to slove it.
