Blockchain.info web wallet holds your private keys??!

[icberg1]

Hello folks,

i'm having issues with deriving the private keys from the seed provided by Blockchain.info web wallet; Iancoleman tool gave me all the privkeys except for the address that held my bitcoin in time of the hard-forks. I already contacted the the support team of blockchain.info and they game me a Java Script command to extract the privkeys (Blockchain.MyWallet.wallet._getPrivateKey(account#,"M/0/index#") but the results were the same as Iancoleman tool gave... NO presence of the subject address which is still listed in my transactions history as my bitcoin wallet!!!  am'i going to loose all my fork coins?

I've tried to contact them again but no answer

Please advise if there is any method to get its related private key
 
Thanks in advance
