I have problems with my profile but I can not find where to contact support. I sent a message in comments 10 days ago and there is no response.
My VPS is frozen.
I want to change my full name to just nickname. It is not possible because the page does not allow deletion.
Now you have stated 3 different problems.

Have your profile deleted and make a new one without seller verification.
Can not move to another account, does not start the current account
The message: Error saving data appears.
You can find a contact method at the bottom of every page.
