I wouldn't even be shocked if they would say it depends on your astrology sign. They are just straight ignoring and running away from a clear explanation. Nothing to do at this point.
I hope these appointments that are booked a week ahead are good signs tho. Also seeing more than one person in the thread writing they got the call hopefully means they are trying to pick up the pace. I am still not convinced with the postal code thing, but seeing V6s and being V7 myself, well, you know. Let's hope!
