Customers have many legal rights when shopping in Germany. They include the right to return goods if they are damaged or broken.
They can also ask for a refund if the goods are defective or not delivered on time. But they can't ask for money back if they don't pay for the goods. The right to a refund also applies if they do not pay the full price of the goods they are buying, but not if the price is lower than what they paid for the item in the first place.
