Dear Rizpar,
can you please share the name of the person who recieved your documents. there a quite a few familiary names like G.Miller, D.Stapleton, Doug...all these names are the same who has been recieveing documents from different forum members and their case has been moved forward.
I think there is no need to panic. relax . well you are right you have to get all your orignal documetns including your orignal IELTS to apply again.
regarding your another query. Please be informed that you have to INFORM VISA OFFICE for all the changes happening in your family. like wedding,birth of a baby. for this you have to ifnorm visa office with necessary documents. personally i dont think so that your case will be slowed down due to such changes but you never know.
Regards,
salman.
