CALABASAS, CALIFORNIA -- I've been paying about $100.00 a month to Grant and Weber since August 2009 for the medical bill I owed at the hospital Sept 2008. I had submit the financial aids application but there was no respond from hospital until February 2010 the hospital finally sent me approval letter that my responsibility would be only about $500.00 instead of $4,000.00. I've been paying Grant and Weber more than $500.00 I am not sure what I should do please advise.
