These guys are well versed in scamming folks that send their mobile devices to them for resale. First they clam it takes 3 to 5 days after receiving to inspect your device. USPS provide tracking # and was delivered to their Processing Center facility in Louisville, KY. After many calls to them they suddenly switched their story to not able to locate my device, and then asked me for original IMEI number of the device which I luckily had from T-Mobile documentation where I originally purchased device. Now claiming the device cannot be located. What a sham business, and do not send your devices to them for re-sale. Customer service people there are useless. They are downright crooks!
