AVG reinstalled-was given the unistall to get rid of the old version-so uninstalled-now I got no as

AVG reinstalled-
1.  I installed the update for my subscription
2. Had an error so asked what to do
3. Was given the unistall link to get rid of the old version-so uninstalled
4. Then when i tried to reinstall the update it would not take it.
5. I Could not get any assistance so in desperation downloaded the free version.
6. Result I have a very slow laptop-The AVG says I have AVG installed but I cannot find in my Programs file.

WHAT DO I I DO NOW AS I PAID FOR THIS RE INSTALLATION 7 DAYS AGO!!! I just want what I paid for
