You have zero chances of recovering your accounts.
Account recovery is not a priority and even those who have provided valid signed messages are waiting for months now.
Read Theymos' post below
https://bitcointalk.org/index.php?topic=497545.0If you want us to recover a hacked/lost account, you need to prove that you own it. Typically, the only acceptable method of proving ownership is by signing a message (including current date and desired new email address) using a Bitcoin address or PGP key associated with the account. A Bitcoin address or PGP key is associated with the account only if the account posted the key/address, sent it in a PM, or if it is still listed in the account's profile.
I very rarely recover accounts if you can't prove ownership as described above. There are alternative ways of proving ownership, but they take too much time. If I point you to this thread, you can't prove ownership properly, and then I ignore your future PMs, this means that I'm not going to recover your account. Create a new one.
The wallet i used its indian wallet and have no sign is feature what i can do that for it. Moreover i never knew that my account going to hack due to bitcointalk data leaks less security system. Its takes month and years to gain higher level membership on bitcointalk
You need a bitcoin address (or an altcoin address should do too) which was posted by you in the forum, posted by the hacked account that is, in an unedited post, or a closed thread.
I have scrolled through your posting history, and you never posted a single address... big mistake.
Honestly, just forget it. As you have been told, there's people with several signed addresses that still got no reply, basically because the recovery system is a mess. Unless you can somehow convince theymos/Cyrus with your so called proof from your paypal/selly stuff, I would say you have 0 chances to get your account back realistically.
