I've just been contacted by one of these companies about an endowment mortgage they reckon I was probably mis-sold in 1994. I cashed it in in 2001, but the guy said I could conceivably win about £2000-3000. He said I could claim on my own, but that the individual success rate is 30% and his company's is 90%. Of course, the snag is that they receive 35% commission (on a no win, no fee basis) and admin fees, taking their fee to around 40%.
Has anyone else successfully claimed on their own, or knows of these kind of companies please?
