This is a case, when I bought BCS on market, I did not realize...

This is a case, when I bought BCS on market, I did not realize any installment reliability - so I just bought on the first day float, when I received contact shows there are two installments have to be paid on due course. So, now the shares in my hand is worth nothing Do you think I am going to pay next two installment, I doubt, possible many buyers on market some as I did.

Please, any advices for this case?

I like that BCS - I hold, I hope that BSC SP will get Higher.
