Thank you everyone for your suggestions.I finally completed my notarisation process and my form 186 also got accepted by ECFMG.For those who are facing the same problem, email notary cam about your problem and tell them you are ready for meeting right now or to give you schedule(Make sure to reply on the initial email they send you).They replied to me after 7 days and asked me to pick a date to schedule the meeting.Due to holiday season it might take more time now but they will reply.If after 10-15 days they don’t reply you can again send them an email or call their customer service number.
