So the answer to both those questions is No then. Why wouldn't you call the department to ask after the allegations you made? Because of course they'd more than likely send you to the link I posted. To jump from there to contacting a minister directly is akin to calling Michael O'Leary at home because Ryanair's first level of customer service lost a complaint of yours. It makes you a crank.
No. But i think her department should investigate my claims or maybe this is unreasonable of me to expect this???
I am married to a non national and i know these friends/relations of her family very well and have seen the very house's that they have built courtesy of the taxpayer.
There's a way of reporting these claims. By your own admission you haven't followed that. Do you need an adult to come out to you to actually type in the words on the form or press the buttons on the phone so you could call the department? Why should that adult be the minister? Grow up.
