I am so sorry to hear that!
But i do hope you have a good excuse why you were 30 min. late on the interview day!
Our file was transferred to a local office a well in Edmonton last Oct. 2011. afer also waiting for a year (application submitted Nov. 2010)and until now there is no news... We are ready for the interview but they haven't requested one... I hope they do soon..
About your question if when is the next interview for you, only the VO knows...
Wishing you the best of luck and just hang in there!
