Renewal Scam (almost)

I renewed the license when the first offer at a special price for two years came. What was debited was the full price for one year.
“Your license expires soon” has been the message popping up in my PC ever since. Piriform then kept bugging me to renew again and again. I’m a bit annoyed that a) they didn’t stick to their original offer and b) that they are unable to differentiate between a current subscriber and a non-subscriber. Also, there is no accounting background on my account page on CCleaner. Definitely going to back to Norton!

Norton and CCleaner are sold/provided-by the same corporation GenDigital.
