corruption on your yahoo account or other account

this kind of mess hardly to never happens to me,but over the past couple of days some turkey done messed up or messed in my account and made it difficult for me to write folks back in my own account. i mean what is this all about? bad enough to just have to read stuff but going without the tools to write back is frustrating. it's like having a stamp on your envelope and the letter is sealed airtight and some fool still opens up your mail and toys with it and you can't get it sent out. i reported this mess and still ain't really got a proper set of action taken care of. i mean i just have to shake my head. this happens on cyberspace and computers do have folks who send virus and other things to slow down your computer,etc... but i was just caught all off guard with this situation.i hope this matter gets taken care of because it is so frustrating to not be able to write back or respond like i enjoy doing. those small things as hitting the reply button now are like taking first steps in a whole different vibe.
