Jace Lillard at the Rock Island USCellular store has been beyond helpful, patient, professional, and knowledgeable -- both last year when there was difficulty with overseas cell phone billing...and again just this month : first, when a major number of texts disappeared and she was able to restore all of them...and then when she expedited the purchase of new phones. Your company is lucky to have her, and she is the main reason we have stayed with USCellular. View on Google
