Vat return

  Dear Sir, While e filing the return for month of February 2017, it is showing that you have already file the return for this period but actually we had not filed the return. It is also not showing in History of return.. No return is filed for the month of February but still this error is showing. We tried by revising the return but it is showing that filed the original return first. we are totally confused how to proceed further. Please help us
