I have been working with Equifax to resolve several negative entries on my credit report. The problem is that some of the entries, that I dispute the origin of, have been sold to other collection companies who are also reporting the same negative entries. 
It has been difficult removing these duplicate entries because the only reply you get from Equifax after XXXX days is that they say they have verified this is " owned by you ''. They seem to be ignoring the other very pertinent information sent other than stating that the entry is disputed by the consumer. 
XXXX duplicate I asked them to remove is very obvious in that the original entry shares the exact SAME information as the entry made by the company they sold it to including dates, amounts and even the account number!! Yet the Equifax investigation I started found no problem with this duplicate entry and again just stated " we found this item belongs to you ''! This investigation took thirty days and was pointless since it ignored some very obvious facts! 
It is also very difficult to submit disputes with Equifax in that you are restricted to very few categories to enter your dispute ( For example there is no easy way to submit that a negative entry is a duplicate entry so you end up trying to guess which is the closest ) and it is is limited to XXXX characters and for some reason it rejects the use of a lot of the regular characters of punctuation ( For example the use of an exclamation point! ) and even numbers ( even though it states these are allowed )! The fact that you are not given a contact person means you are at the mercy of their very difficult and slow system and a XXXX sentence reply is not enough. To state, in your investigation " we have determined this debt belongs to you '' is insufficient when you have let them know for example : that a Cell phone company has put fraudulent charges on your bill when that same company is settling XXXX with it 's customers for that very same reason! Well they definitely " phoned in '' this investigation! 
These credit reporting agencies have a lot of power and literally hold our lives in their hands and should be held to a much higher level of accountability!
