Yeah, unbelievable is the word!!! I applied in October 2008 and London didn't start processing until January 8, 2009 . . . and we're still waiting!!!
No, I haven't had any correspondence from London since the postal strike, and believe it or not, I have never had anything from London at all. We always had to call in or write to find out information. When my husband's interview was scheduled they were supposed to send a letter out to him telling him when and where the interview was supposed to take place, but he never received that letter. We're lucky that we found out before it was too late.
If I were you I'd try calling London and asking them what's going on. Or you can write a case specific enquiry. Did you have an interview? If so, did the person that conducted your interview give you their contact information (phone number or email)? If so, then you can try to get in contact with that person to ask what's going on. That's what my husband and I do right now, we always get in contact with the man that conducted the interview every now and then to see where our case has gotten.
