I was using blockchain wallet for 2 years and everything was fine but 15 days ago they have some problems with there wallet.
I couldn`t login for 2 days after that they gave mi new address, i tried to import old address to use and they put it in watch only and now i can`t get my funds.
I most say that my comp crashed and i lost my private key.
Their support would not even hear me, said they can not help me and that's it.
Even your computer got crash or wreck, it doesn't have to do with your problem since all your backup are generated online. You are using web wallet here and not a desktop application or something like that.
Didn't you managed to save your magic 12 words key? It's a must and one of the first thing to do when dealing with the services of blockchain.info. Try to contact their suppor then.
wait, how did you lose your private key with blockchain.info?
do you mean your wallet identifier? it should be in your emails at the bottom.
