GSTR1 error - invoices already submitted

Due date to file GSTR 1 extended till 10th September. Hope to get the issue resolved by then.

I am trying to file gstr1 return for July 2017 on system portal. 
I have saved and successfully submitted the data. 
But when i try to file the return with EVC option and after entering the OTP received, the message come on the screen is " Error, invoices already submitted". What does that mean ?
I have tried this for 5_6 times but every time same error pops up.

Mailed Twice and Called Twice. No reply. 

Tweeted about the same. No reply

- I have prepared the return using Offline Tool and checked all the details to match with Tally
- Submitted the checked GSTR 1 after generating the "Preview File"
- No Errors

- While Filing the GSTR 1 Return using DSC or EVC, it shows this "Error ! Invoices Already Submitted"
- I called the helpline no. and they said that this is a common issue from their side and will be resolved soon.
- I e-mailed them as well but have yet to receive a reply.

Please let me know what can be done to resolve this.
Thank you.

 

Also, the dates have been extened by a few days so "Hopefully, Not to worry". It is better to worry though.

From morning 11 am till 8pm I have been able to file 2 (two) GSTR 1 with DSC successfully after trying for more than thousand times. Entire day lost  in filing two returns only.

Though government has extended the return filing timelimit, its not question of timelimit extension, its question of system preparedness by gstin. While inaugurating GST , FM said that everyone should have started to prepare their system for gst upgradation six months before actual appointed day. But government itself is not prepared for the same and result is this type of andhadhundi. Surprisingly, no one including CII, FICCI, trade associations, CA associations have raised this issue in the last three days. Every taxpayer is frustrated due to this system failure. No one is against compliance in stipulated time but not expecting this type hardship. टॅक्स भी दो, उपर से परेशानी भी भूगतो।
