Question please...a LARGE company sends you an invoice for charges they KNOW are not legit. They refuse to correct the charges even when their own records show the cahrges are not valid. The company browbeats you and then turns the account over to collectors who browbeat you worse. All the time you can prove the charges are not valid. Now the issue is on the credit report and have had to change phone numbers to stop the harassment by collectors. This company is so large they just think they can do what they want and no concern if it's legal.
Is there anything I can do about this? Thanks!
