I bought several phones from this store without ever having a problem. Then, in July 2018, I received a defective telephone ( 110), purchased from the German warehouse: after several emails and as many attempts to solve the problem via software, they asked me to send the phone back to their warehouse in China ( 30). After a few months and several reminder emails, the phone returns with the exact same defect when I sent it. Despite countless requests for reimbursement, they paid me with a 20 coupon, which I declined (February 28,2019). Unprofessional!
