WellNow sent disputed charge to Collections
I have been actively disputing two charges with WellNow since I received the initial bill for the charges (I believe in Jan or Feb of this year). It has been documented by WellNow's billing department as in dispute and I have called several times to request updates and continue disputing the bill. I just called again as I received a new monthly statement which is typically when I ask to get updates/reconfirm that the charge is still being disputed. Today they told me it was sent to Harris & Harris for collections on 5/1. I know this shouldn't have been sent as it's in dispute but they said they can't get it back and gave me the number for H&H.
My question is: Is it worth calling H&H immediately or should I wait until I receive physical mail to start the dispute with collections.
