I also want to express my appreciation of the program "from A to Z Guarantee" from Amazon. I ordered the product the first time one week before Christmas (bad time?), The parcel in Fréquencéo (delivery mailbox without signature) never happened contrary to the claims of the monitoring and reporting. After various fruitless attempts (exchanges with the seller via email from Amazon, complaints to the Post Office), I called the warranty of A to Z. In the next minute I was refunded in good d purchase, which allowed me to place a second order, although arrival. While the sum involved is small and it's the first time I called, but it's nice.
