Central Portfolio Control Inc. Debt Collection Complaint

Central Portfolio Control Inc. Debt collection department,

Medical Disclosure verification of debt Not given enough info to verify debt Texas

I received a letter, collection letter from Central Portfolio Control, they stated that because of interest, late charges and other charges that may vary from day to day, the amount due on the day you pay may be greater. In addition, this is the first time I have received a collection notice on this amount and have not received any information on when the service was/if it was provided by the Hospital they are collecting for. They want me to send in a payment and then discuss options? It does n't even give the date of service..
