My mail id got hacked and the hacker change every information including my mobile number too.Now I called customer support and the only solution they told is to buy a security software which is very expensive for me.I want to delete my account but i can't do that.They are just stick to one solution.Is that is expecting from a renowned company?They are not there to help us they are there to do their business ans sell the software.and i will definitely write and article about this so that no one get harrased like me and not to open yahoo mail.
