I can confirm also that comment about the mishandling of documents!!
My flatmate had a two week period before his visa expired where he reminded Expertise staff REPEATEDLY that it would soon run out, but they kept to the frustrating old "someone will call you about it tmorrow" routine. Eventually when the application was done he was told his visa had actually expired and his application was too late, and so he had to go through all sorts of trouble to get a new visa. Personally I don't like the fact they kept our passports for so long, it made me uneasy!!
