*****ulent stop order

I'm a government employee,and today I checked my salary advice and I found out that Scorpion is deducting money from my persal,I have never spoke or signed anything with then,I don't need their cover they are *****ulently debiting money from my salary.They don't even have my correct contacts on their system,this is very frustrating how can a legal services company commit such *****. I want my money back.
