My sister was billed over $100 a month for over two years for a modem that was sitting in a closet because a technician said it was outdated when she asked him if needed it back after installing a new one. She was not aware that they continued to bill her for the old one as well as the new one.
They claimed they could go back very far to give a refund.
$3000 overbilling and they won't give any of it back? That is disgusting.
