Internet Security replaced by Trial Version

I have not used the community before, until now when I found my Internet 3 user, had been replaced by a trial version.
There were some posts and answers stating try uninstall and clean out AVG programmes, then reinstall AVG.
Only I found the circle of doom growing ever bigger, when all I got was the same issue. I tried my subscription, again! 
Congratulations you have AVG Tune up ending 20 blah blah blah.
Surely in this digital world you would also have a copy of my AVG Licence, I should not have to provide proof of purchase; which I do have. 
The licence key won't work and I can't re-activate as it is set to free trial. 
But if you spend Just £19.99 SAVE £40.
I am not paying for something that is already paid for until September 2019
As I see it, an update wiped out shed loads of data which you want us to pay for.

We are here to help.
Please update your program once (Open AVG Internet Security > Menu > Settings > Update) and activate the subscription using the license number which was just sent to you via an e-mail.
Revert to us for further assistance. Thank you.
