The belt has walked 10 times or 10 days I contacted via the Amazon VIAFORME provider. 1/2 after two months I expect this form allowing me to return the parcel he had to send me free! No answer my mails nor Amazon nor Viaforme despite a telephone reminder. Lost 71 euros. I tried everything, I am disgusted and more .. delivery had not been respected. I was a loyal customer Amazon, I now command on other sites !!! VIAFORME this is not the form of monitoring customer!
