Your case will go to Home Office, as registrars have no discretion over it. Don't worry, most people in your position gets quickly approved, nothing like 70 days. 1-2 weeks is more typical.
I am not a regulated immigration advisor so only giving my own view which should not be relied upon as advice. Sorry, but I have disabled my private and visitor message functions so you can't send me any. If you want advice, contact a registered immigration advisor: http://oisc.homeoffice.gov.uk/
