I couldn`t login for 2 days after that they gave mi new address
Don't know what you mean by this, they give you new address to receive bitcoin as receiving address? It is normal to have different address in their HD wallet.
i tried to import old address to use and they put it in watch only and now i can`t get my funds.
You need to import your private key not address, if you only have bitcoin address your address will be imported as watch only address.
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.
- If you lost your private key than you will lost access to your bitcoin.
- They can't help you because they don't store your private key in their servers.
