DEMANDING MONEY

HELLO , I see that many other people are experiancing the same problem as I am , I asked them for a signed document from me entering into this so called contract with them bit they refuse to furbish that , I mean come on guys in today's time it is so easy to buy innocent peoples details , I also asked Lifestyle Legal to show me since this account was created when exactly did I use any of their services which they cannot furbish as well . They are sending me threathening emails and sms's demanding moneys from me .They will not get a single hard earned cent from me , Legally it is my right to request a signed document by me which shows a binding contract with them. <br> Guys please how can we stop these people from just demanding money from people in this difficult time ?
