Ajay Kumar,
It appears there might be a slight confusion regarding the charge on your statement. The entry, Canva*, suggests this transaction is related to Canva, which is a graphic design platform, and not CanvasJS, JavaScript charting library. We suggest you verify the charge details once again.
However, I have forwarded your request and the details provided to our Sales team. They will look into this matter to see if there is any potential confusion regarding CanvasJS licensing and will get back to you directly via email for further clarification.
Feel free to drop a mail at sales@canvasjs.com, for more sales related queries.
