Query: Bad QC, technical support even worse

Less than a month after the purchase, the base-unit button for retrieving the message stops working. Manufacturer's technical/customer support is practically non-existent. The limited 1 yr warranty provides only a replacement with a refurbished (NOT NEW!) product, and only if the customer mails the phone to their TX center, at own expense. Panasonic, shame on you!!!
