deactivation
I need help reactivating my accounts i called yahoo customer care and got several cases and they replied to my issue by mail telling me that my accounts (about 20 yahoo emails all deactivated) that i violated terms of service wich i did not do im sure. the problem is that Yahoo Technical Support Team are not believing me and taking FALSE ABUSE REPORTS by haters or hackers seriously and this is not fair and innocent people are losing their accounts. I wish deactivation on abuse reports are taking in further and deep investigation not from how many fake abuse reports they receive
