Getting deals out of T-mobile telesales

[Guest DancingMatt]

Has anyone ever haggled/negotiated/got anything extra from the official T-mobile telesales? I'm surprised they're so immovable.

Really, have you ever managed to get a deal out of them, say more than 12 months half-price, or a free text bundle on top of your tariff? Or anything "thrown in" on top of the advertised deal?
