My wife applied on the 29th of July and was given the hard sell tactic of "it will take 10 - 12 weeks unless you use the priority service". She resisted the hard sell and received her visa on the 25th of August. We did use the charged email service and we emailed daily after fifteen working days had passed and received generic replies. Overall we are obviously very happy to have received the visa but we do feel a little aggrieved with having a hard sell tactic which goes against the official notice of waiting times being 7 weeks with an effort made to go back to fifteen working days.
Best of luck to all of those waiting and applying.
