I have got an pdf file from this email and they call me and tell submit at Nov 1-2017. I have done and submited to this email for 3 days they again call me and told to pay the GST amount 3500 and also told to submit your a/c details I have submitted and they told me amount will be credited on 20th Nov when I call then it was switched off all were blocked I have tried till 29th it was again it was switched off so they have cheated. So take action about this company so others can beware of this company Thank you......
