My subscription was going to expire. I renewed my subscription and they still kept calling me! The problem was that I didn't activate my renewal. I didn't read my confirmation email as I figured I already had a technet account, just renewed it, I just filed it for records. Guess you need to activate a renewal too!
I do have Technet but didn't answer. If this is them and they harass like others have stated, then I will block their number.
Technet has gotten worse every year, and is no longer worth it. It's become a waste of money. If you subscribe now (unlike in the past) your keys will expire when your subscription ends. That is total theft by Microsoft,
