Was the sync up device New or used? also are you entering the IMEI# from the sync device? I'd contact support again, and if they can't help asked to be escalated up. Good luck keep us posted.
Sorry this is giving you grief, but we do wanna make sure this gets taken care of. nelfar212 asked some really good questions and I aggree that giving Tech Care folks another shot at fixing this is a good idea. Please give us a reply back and let us know if this is working. Thanks.
