PORTSMOUTH, N.H. (AP) — A New Hampshire woman just couldn’t believe the nearly $2,000 bill she received for a bottle of antibiotic pills was right, so she persisted in demanding answers.

In the end, it turned out that Susan Chamberlin should have been charged $382.50 by Portsmouth Regional Hospital.

Chamberlain says she was shocked when she first got the $1,912.50 bill for a bottle of cefuroxime pills given to her daughter during emergency treatment.

Chamberlain made several calls to complain and find out her rights, and finally asked Seacoast Sunday (http://bit.ly/ozco2X ) for help.

A hospital spokeswoman says the overcharge was due to a billing error.
