<p>happymom1 brings up a good point about whether this is even legit. Maybe a good starting point would be for the ‘parents’, i.e. not the granddaughter or anyone else, to contact that hospital that performed the procedures and find out from them if there was any money owed and if so, how much it is/was and what the current status is - i.e. did they turn it all over to a collection agency and if so which particular one and if not, if they know why this collection agency is contacting the minor and how to go about paying the bill.</p>
<p>The above should be a cheap and easy starting point.</p>
