Is it legal for an electric company to transfer a balance of 480 for an 11 year old past due account
Whose account was it?
to a non family person ,no relationship..but I'm living with?
You're living with somebody your not related to?
Was the account balance transferred to you or to that person?
Are you in the same property that the old account was?
Who is doing the harassing?
Who is us.
saying collections ppl coming
Again, who is saying this?
Coming where?
To your house?
To knock on your door and ask for money?
Do you mean "garnish" wages?
That takes a court order. Has somebody been sued? Is there a judgment?
after I told them I was on ssi disabled
Who is "them"?
"Telling" somebody something is meaningless if that somebody hasn't done anything yet.
What did the utility company tell you when you asked about all this?
Better yet, maybe you should find somebody who has better writing and grammar skills to write this story for you. No offense. But your post is incomprehensible.
