I need to re-download the Version of 360 I purchased, I only get 360 Premier as a trial

I have been using Norton 360 for a number of years without complaint. Recently Norton stopped working, ie "unspecified error" message.  I decided to re-download the software.  I selected Norton 360, it downloaded and started. I was asked for the Product Key, so I dutifully entered the 25 character key and the reponse was that that key was for a different product, as THIS was Norton 360 Premier Edition trial version, NOT what I puchased which was regular N360.

 

I had the option to locate the product for the key that I have.  It downloaded and lo and behold it was the N360 Premier Edition,

Trial Version.

 

Next tact was to logon to MyAccount, go to my purchases, select the link for the product I ACTUALLY purchased.

So I downloaded that. No such luck, guess what, N360 Premier Edition trial version.

 

My original purchased product, complete with subscription expiry shows in MyAccount, which I can't get reinstalled and now I have this trial version of N360 Premier attached to my account and installed.

 

What the *&^%$# is going on.

 

Why can't I get what I paid for without so much hassle?
