I don't understand it either. It's not like they don't know that our extension ran out! They need to make this whole process easier- if they can't be bothered to get us interviewed in our extension timeframe then just automatically send us a new one. I'll be glad when this whole process is over! My lawyer had to shout at them to get me that stamp, not sure it would go down too well, if you tried it! Just keep bugging them- ask for a Tier 2 officer when you call. Sorry, that you are having a hard time with it.
