Profile info change problem

I can’t change my profile info at all it shows "The change you wanted was rejected.

You may have tried something you don’t have access to" I want to change my username as a company name mrakhil2999 to WPCred that is my website. I want to create my profile as a business so that I can contribute but your system does not allow me to do this even if I change my picture and add my website WPCred shows that message. kindly help me. Basically, it is a blog site for WordPress Themes and WooCommerce plugins. if I can’t change my profile info I can’t contribute here anything or engage with the community as well.

@mrakhil2999 we will look into this for you.
