From the NZ Herald:
Telecom is reimbursing 150,000 broadband customers after a technical fault over-calculated customers' broadband usage through November and December.
The customers were either overcharged or had their internet connection reduced to dial-up speed.
Telecom said all customers affected were being reimbursed and had their data usage allowances doubled for the following month.
Interesting. I am on Big Time - I supposedly have no cap. I wonder how they're going to double that.
