Delinquency notice from new water company?

Has anyone else received a delinquency notice from the South Orange Water Utility?  This is the new company, not the old one.  They threaten shutoff, referral to collections, and tax lien for unpaid bills.  But my bank assures me they paid the bill 2 weeks before the date on the letter.  Just wondering if this is a unique to me issue that I have to fight or if other people have the same issue and they are aware so it might resolve itself. 

Have you called the phone number on your water bill (not the number on the letter)?  This could be a scam or it could be an error that can be resolved over the phone.

I thought American Water took over operations and billing for S.O.? 

^^^ They did.  

They did, but billing is through the South Orange water utility.  It's a little odd, with a mailing address in Pittsburgh and a special customer service number.

I just put in a dispute with my bank and they will take care of it, but I was interested to know if I was the only one or if this was a bigger issue.  Thanks.
