But why should we have to pay £50 for one months usage! You could nearly get unlimited adsl on sky for that!! There must be something that can be done
give and take on low usage packages, usually they are a lower monthly base price but more costly when using them more over agreed limits.
pre purchased bandwidth on most internet services is cheaper than post usage.
What you can do is either pay the bill and learn your lesson, or upgrade the package and BT may as a goodwill waive the current usage bill when they know they going to get extra monthly income off you. You may have to do both tho if BT dont offer a goodwill.
