Hi there! My name is***** am a computer professional with over 15 years of experience with both Mac and Windows computers, phones, tablets, and printers, email issues, software problems. etc. It would be my pleasure to assist you with this. I'll need to ask a few questions in order to best help. Is your account locked because you have entered an incorrect password ***** many times? Or sis you receive an email from Yahoo telling you that it was blocked for some other reason? When is the last time that you tried to access the account?
