October month filed.but it shows submitted

I had filed my October month GSTR-3B return on 20/11/2017, and even received mail from GST portal and got ARN. However even my status for October month was changed from FILED to SUBMITTED.

I called GST helpdesk, but no one answered. 

Here is the mail that I received when filed October return on time.

You can check above mail which is for October month filing and filed on time.

Again when I tried to file my November month GSTR-3B, I got error message that return for previous month was not filed.

I had file my October month return again. You can check the mail that I received again for refiling.

Dear Applicant/ Taxpayer, 
GSTIN

its really surprising to see GST portal has not recovered from technical faults and tax payers are suffering. Clients are losing faith in consultants.

I had to pay late filing fee of Rs. 1500 for fault of GST network. what do i do
