Has anyone ever emailed the British Embassy?

OKAY sorry ya'll DUMB ars* QUESTION. Has ANYONE ever used that email form on the Embassy page? Instead of spendint a couple of bucks a minute i rather just get an answer u know.
 If you have used it. How long should i HOLD MY BREATH for an answer?
  I just emailed that I was visitng my family in the US and my arrival  date was March 18, and i had a return flight in August. I was not aware of the 90 day limitaitons and if i needed any information to bring with me to London on my arrival. something like that.



Thanks

I had to explain a lil more that I would be coming back to the uk in AUgust.
 SHe just said if i wasnt in the uk by my extention date. i would have to reapply. LOL
THSATS NOT WHAT I ASKED CHIC! HAHAH
 SO i helped her a lil more without telling all the biznass.
