Gst status " migrated" what next

Dear Friends Good Morning. Finally I have successfully uploaded my documents and my application status has become "migrated " from pending. What I should Do now ? I am from Maharashtra. I have one crucial issue as well and will appreciate if someone could help. Person at my CA has created login first time in GST portal . He has put his cell no & Email id. Now he is no more working with CA. I have changed email /mobile on ACES website , I have also put my Email / mobile in enrolement portal while registering for GST. Unfortunately all OTP ( for password reset and other) are diverted to original No. & not to my email / cellphone. What Should I do ? I have raised this concern to GST helpdesk but I think they are so dumb they did not understood exact issue and they replied vaguely. How I can change EMAIL /Mobile on GST Portal ? ( though on ACES site shows my no) I could not find change mobile /email while finishing enrolement process. Thank you Regards varad
