National Platunum

Has anyone had any problems with a company by the name of National Platunum services taking any money out of their accounts without any authorization?  Well, over the weekend, this company took not one but two charges of $99.95 out of my account.  They have caused me to go into overdraft and my bank then charged me $25.00 for each charge.  I contacted my bank but they told me that there was nothing that can be done.  I have attempted to contact the company through email and from the phone number on the email and on my bank withdrawal.  I just don't have any idea what to do.  I don't have any money for my bills, medications, or Christmas gifts.  Can anyone help?
