Frequently Asked Questions for stiftung warentest radiatoren Stiftung Warentest warnt: Was Sie beim Heizen mit Strom beachten sollten
What should I record if a purchase-related problem happens only sometimes?
Do not assume a repeated coincidence establishes the underlying cause. Check whether support has already asked you to stop further attempts.
How can I decide whether an optional addition is useful?
Review the extra cost in the complete order total. Ask how a change to the main order would affect the addition.
What should I clarify if I need more time to decide on an offer?
Avoid sending repeated extension requests through several channels at once. Use the same reference when communicating your eventual decision.
