Someone is using my license number.

Hi,

In 2017, I bought a discounted package Photoshop Elements 14 and Premiere Elements 2014 at local store. As I remember, the package was new, wrapped in foil, etc. I still have the receipt, box, DVDs with serial numbers labels.
I activated both applications on the Adobe website in my profile few days later, I installed and worked 2-3 years until my computer was crashed. During COVID-19, I didn't feel to need use these programs, so I didn't install them on the second computer until the day before yesterday when I diligently needed to test my daughter's new graphics tablet.
It turned out that PSE14 is missing on my list of products.
I tried to explain it on chat and found out that my number is assigned to a different account, from 2015 and they can't help me.
What to do now?
