A defective product, it is not his fault. But the non-compliance of its customers, yes. Seller who does not reimburse the return shipping costs, (but the only object) whereas it was stipulated. I really want to report it to the DGCCR, for a small sum I will draw anything, but they will open a file on him and soon there will be many complaints, they will go home and he will remember long. In addition it took about one month to trace back, if I had not had the tracking number Colissimo, I will wait again. It has to be more respectful of our customers and respond to emails more accurately.
