But i don't understand if I do this will my funds be there. The bookies has sent me already the coins.
And after that email nobody answers my other emails. Does anybody had same problems and what do you think will happen with my balance if I restore it via the 12 word recovery phrase.
Actually, It's a common problem in blockchain.info and if you'll browse the threads in this board, you'll find lot's of users who had the same problem.
Problems like this will continue to arise as long as you'll use blockchain.info, better switch to a new wallet like electrum or better yet to a hardware wallet e.g. ledger, trezor.
What the blockchain.info's support says is true, you can restore your wallet using the recovery phrase or
the seed.
You can use the link they gave you to recover it but as I stated above, I'm not very fond of their wallet so in this case I'll be recommending
electrumHere's a step-by-step- tutorial:
