Two accounts with different mails

Need to delete my main acc cause I dont remember the mail attached to it. Got another acc but dont wanna pay double up. Looked around but cant find anyway to contact spotify

Need to contact someone because I originally would pay monthly for my husbands account but now I upgraded us to a family account and I dont want to have to pay twice.  How can I stop paying for the account my husband has and only pay for the family account?
