pls do not worry,a call from humanrightpresident has nothing to do with cheque bounce case,
as far a your 5 cheques with her is concerned ,it will not be any help to her as you already cleared her balance.if she is asking for more 3.5 there must be legal outstanding liablilty,if there is no liability then you do not have to worry,as she can only claim the amount which you are legally bound to pay
