It looks as if you still have items for sale so it doesn't seem to be a permanent suspension.
The biggest issue is that you had two accounts, trading on both and clearly a business but you have a private Ebay account and a 'no returns' policy which is unlawful.
Upgrade to a business account and sort out the ID issues with Ebay and that may resolve your issues.
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
