Have account with XXXX XXXX XXXX XXXX - XXXX. Original bill was {$1200.00}. Insurance paid {$900.00} leaving an approx XXXX balance. I have made regular payments on this account and have a balance of {$100.00}. They turned this over to collection agency. They encourage you to go through the website and pay on XXXX which I do every other week. When you pay it does not give you the option of which billing, which invoice it just takes the payment. They state that all of my payments have been going to this account with they turned over to the collection agency. They are doing the same thing to me on the hospital billing it shows I owe {$1600.00} which I have been making regular every other week payments. The portion that they applied my payment to they have turned over to collection agency for {$1100.00}. My balance on my account with them still shows {$1600.00} which includes this {$1100.00}. So they are telling me I have to keep making payment to them on the {$1600.00} and call and make arrangements for payments to the collection agency for the {$1100.00} as well. None of this makes since nor is it fair. I have made payments they have applied them where they want them to go and they turn them over to collection with no notice. What can I do??
