Still struggling after 4 months

I was incorrectly billed for cancellation fees and a device fee for a contract older than 3 years.<br> <br> I was blacklisted with no notification from neotel. Since October I have had no communication as to any outstanding amount so I can settle this account, and every month I am charged a penalty fee.<br> <br> Big corporate trying to bleed me for money, when they failed to notify me of any outstanding fees.<br> I will get hold of a senior manager, and I will seek legal advise on this matter.<br> <br>
