we have 4 high en accounts for sale btween5.8-6.5m

Are the account still available

What you need to do to sell the accounts, is the following:

(Assuming you have an account attached to one form of login)
1. Create a dummy account (FB or email, whichever is not currently linked) and link it to the MSF.
2. Message support and ask them to unlink the account from whichever form of login you dont want to give away with the account.
3. Provide all information they ask for. Its not a lot.
4. Link new account to MSF

It’s still linked to your existing emails, can’t unlink. If someone wants to take the risk of buying an account you can still log into then sure but I doubt people would make that choice.

that will work i think..

You can’t unbind accounts. You sell by giving them your google play login(email) or FB login(email as well) or gamecenter login(needs email). You get the idea, need to give up email or can’t sell.
