file cased on 25 May 2010, received 1st file number on October 2010, but i didn't saw that one and nothing happened, then recently 15 July 2011 they send me an official letter from UK office acknowledging that my case was refiled at UK office this time rather than Australia office as the first time.
The information above and the original post slightly contradicts - here its says the original file was submitted on May 2010 but in the initial post , you have said that on speaking to the agency they agreed that it was not filed on this M/Y and a new file number was provided at a later date. Not quite clear about the sequence of events?
If the agency has filed the application prior to June 2010 ,when 0213 was in the MI list - you are good and from reading through others experience, the delay in processing applications prior to June 2010 is inevitable due to the change in approach taken. It is advisable to contact CIC for an update so you would get to know if the application is with them as communicated by the agency & in addition, it will help the case to be looked at, if it is buried down a huge pile of backlogs.
You should bring the changes to CIC's attention at the earliest. If you have a file number then contact the VO via the mode they have asked to (email, fax ,post )
