I think its still impossible to recover if you don't have the seeds to recover your blockchain wallet..
Did you try to contact the support? or contact them in facebook you can found here

I saw same issue before just new and i think he still not recover his wallet because he forgot where he save seeds..
So next time be careful when saving seeds because its really important.
