Ignore all the terrible advice here Haz.
The simple fact is 'Yes' Ofcom will remove ANY HM at any time, so long as you call during office hours, and use their free online voucher code 'UR1' when you speak to Shirley Knott.
Please note however, that you can only redeem this voucher 3 times per series of Big Brother, and there's a strict No returns to the House policy - so be sure to select carefully when calling Shirl.
I've temporarily misplaced the link which proves all this along with the phone number..however if you Google the code mentioned, you'll quickly find the necessary info.
Can you give us a heads up when done also. Many Thank Yous
