Your license has been extended in the moment you accepted the quote and received the invoice (on 21/02/2022), and it was still valid until 14/03/2022 (due to the temporary extension we provided).
You didn't get a new license key because you renewed your license. A Customer Service agent did explain this on 08/03/2022 at 10:56, answering your email from 07/03/2022 at 11:40.
I saw another conversation you had with the Customer Service Team in late February. That was when you got the quote for the license renewal and the free-of-charge 14-day license extension.
If you sent emails between 23/02/2022 and 07/03/2022, please let me know. I'll gladly ask the Customer Service Team to look into it.
A support agent freed-up an activation on your license and asked you to perform a new offline activation on 21/02 at 16:02h, following up on your email on 21/02 at 14:39h. That would have been the solution to resolve the problem.
I can understand that this situation must have been frustrating. However, this is not the Customer Service Team's fault. They're doing a great job, and they did always answer your emails, trying to solve the issue in a customer-oriented way.
