The graduations on compensation for use of insurance as I feel perfectly fine, of course, one wishes the customer more, but an insurance nunmal no charity.
I had bought the warranty extension together with a vacuum cleaner, this then but returned, the "return" of the extended warranty went as easily as the back end of an article to Amazon.com: As usual, use the Return Center and return the items, two days later had I ERGO an email about the confirmation of the cancellation, and shortly afterwards the 10.49 Euro in my account.
