TDS - quarterly returns - Mistakes - Scope for revision

Few mistakes like date of deduction etc. has been made while filing qtrly. return because of date format problem in excel. The file has been uploaded successfully in nsdl. Now while taking print out of certificate, mistake came to light. I tried to revise and upload the return. The  revised return was uploaded with the changes, but after somedays, nsdl site says return rejected. What to do now ? Should the cerificate be issued with correct detaisl (which will vary with the records files with nsdl) or should the certificate be issued with wrong dates as filed with nsdl (in that event the vendor will raise dispute). I am in dilemma. Pl. suggest what to do ?
