Flawed dispute process

My frustration is increasing with the way in which this dispute is being handled. Firstly, my communication on this matter began on 25 October however dispute was only raised on 31st October. Secondly, I receive an email saying the dispute has not been resolved in my favor however the credit responds on the evidence that it must be removed!!! I want this dispute sorted out today please and the flag removed. This information should not even be there in the first place.
