Hello, i'm in need of Help or understanding of my problem.

I Registered a wallet on Blockchain , i used to receive 3-4 payments total of $400 to one Bitcoin Address " the first one BTC gave me to receive one and i have been using that address to receive money since then , i saved it in a txt file and i received all payments on it.

i protected my Wallet with 2FA , a code is being sent to my cellphone every time i need to login , yesterday i tried to login but the code didn't arrive several times to my phone and my account was locked for 4 hours. i slept and woke up next morning trying to login , same problem code didn't arrive. so i back up my wallet with my private key into a new one with a new email.

the problem is my $400 was sent as following



17JEN that was my address i receive all my transaction on.

the other 2 address are the one which blockchain backed up

1Pa8Z "Address" now has only $2 on it
1KvZX "Address" has all the rest 398$ on it

My Final Balance in the wallet now is $2 which i can use and the other 398$ are gone. i cannot send them and i can't see them anywhere.
