Who has released your dates?
Mine were finalised until last week when I was told to "...hold until further notice, we will call you up when we want you..."
Great! Although when the question was asked about time scales i was told to ring back in 3 weeks and I would know more.
I asked about AT but I have been informed that if I am out of the country when I am called forward they will just call the next person on the list and I will go to the back of the que!
So, sit and wait doing nothing...until further notice!
