Its frustrating that after 8 working days and still no emails at all...im guessing some people do not even get emails at all though and its a busy time of year so could be taking longer....everything in the uk moves so slow!
It is true, everything does tend to go more slowly here! My best suggestion is take it as a learning experience for what it will be like to live here! Everything takes more time than you would think. So patience really is useful. I remember how frustratingly slow it was, I too was chomping at the bit and annoyed at UKVI for the delay.
My advice from experience?
Distract yourself! Spend as much time doing things in the US that you won't get to do once you move. Spend time with friends and family, eat at your favourite restaurants, watch the TV shows that AREN'T on UK tv or UK netflix. (seriously, if you didn't already know, UK netflix blows compared to the US). You'll be missing all of that before you know it from the UK. Video chat is awesome, but there is nothing like being able to spend time with your favourite people in person.
And as larrabee said, if you were going the other way it would be up to a year long process, seriously. That was part of the reason we chose for me (USC) to move to the UK. Only a small part though.
Best advice--Haunt the UPS tracking site. Check it everyday for movement (except weekends). You may end up like me & find out there first.
This advice only works if you used VFS global for shipping. I didn't, because it was MUCH cheaper for me to post it myself. My return shipping was about $75, they used the shipping option that takes 1-5 days rather than the 1-3 days.
