Query: Buyer Beware

My phone was purchased in May 2001 and first went wrong in September and then again in December.Unless you are willing to pay and additional $25 to get a replacement you have to wait for them to send you a box, return the faulty phone and wait for them to send you a replacement. Note I didn't say NEW because they reserve the right to send you a refurbished unit which has a sticker stating No Warranty. My unit also came with one corroded battery rendering it useless.All in all the phone and service are totally useless and Siemens customer service is useless
