Strategic cancellation: Get cheaper contracts without switching providers. If you want a subscription or contract with your provider with better conditions, it is sometimes worth canceling completely.
The providers don't want to lose their loyal customers and in such a situation they make concessions so that they don't lose them completely. If the provider does not respond to the customer with a better offer, the customer will then have to look for another contract. According to Aboalarm.de, customers save up to 50 percent if they cancel strategically and get new offers.
