Adobe account help

Over the last few days I have become aware of some odd behaviour in my adobe account and I am concerned that either my account or my computer might have been hacked. Under my signed in activity and register devices. I have tried calling customer support and they transfer me to the Technical department and I was told to call back in three hours because the technician couldnt  see the information, he honestly suonded like he had no idea of what to do, well I called back and to no surprise they didn't answer. I have changed my Adobe password multiple times and enabled 2 step verification. I have also scanned my computer with various antivirus and antimalware software without anything significant being detected. Has anybody else experienced anything like this? I don't know what's going on here and would be grateful for any advice.
