How to submit a complaint with Spark NZ

- Anchor the facts: Include account details, bills, screenshots, speed tests, and prior emails and explain what went wrong with mobile, broadband, and landline connections.
- Name the complaint theme: Say if the issue is about network coverage, slow internet speeds, and customer service response times so it is routed properly.
- Ask for a concrete outcome: Spell out whether you want a bill correction, refund, service fix, credit, or a clear written explanation.
