I have Norton 360 w/Lifelock. Windows 10 operating system. I renewed my subscription but Norton Utilities Premium still has old expiration date when accessed. I followed instructions and deleted and downloaded w/new key. It said Norton Utilities ready for use but when accessed - Result is same: old key and expiration date still listed. Under subscriptions it says Norton Utilities Premium disabled but doesn't give a way to enable. Did this three times and result still the same. Cannot find a phone number to contact Norton support under either support or contact us listings. Please advise.
