Merchant account closed with payments on hold for unknown reason!

My merchant account has been closed unexpectedly and I have client payments that were already paid but not deposited to me! 

I have now read countless issues of people in the same position as me, and no one seems to be able to help. I have a large payment on hold in my account since last week, even after providing the requested bank statements. Only to log in a few days later, and see my payment deposit is on hold and marked as 'EXPIRED' . I am told my phone representatives that my merchant account has been closed for an unknown 'business decision'. This is awful. I feel I have just been ROBBED and will never see that money I worked so hard to receive. Truly horrible service. I am praying  someone can resolve this for me.
