New Zealand's competition watchdog has filed 11 charges against Spark, alleging the telco misled customers.
The charges were filed in Auckland District Court by the Commerce Commission under the Fair Trading Act and cover the period 2 June 2014 to 7 December 2017.
The Commission says the charges arose from the following three issues:
• Spark overcharged customers for broadband data when a fault in Spark's broadband network misrecorded customer data usage.
• Spark sent letters offering new customers a $100 account credit for subscribing to a particular broadband plan but failed to mention the offer could only be redeemed by phoning Spark. The offers allegedly created the impression that customers signing up online would receive the credit, when they would not.
• From 2 June 2014, Spark's terms and conditions said charges would stop 30 days after the customer gave notice to terminate their contract. However, the Commission alleges that the customer's final bill included charges for the entire next monthly billing period regardless of when the Spark service stopped.
Spark said it had already applied credits to the accounts of all impacted customers and, for former customers, has made extensive efforts to return all money owed so they receive the benefit of their credit.
