Bad service

I have struggled to get my dispute resolved. I have written a review on 15 March 2021 about the account that has appear to credit profile that I do not opened it on February 2021. I called the call centre to lodge a dispute. They have lodged a dispute Ref TU*** and I was told to send the supporting documents. I did send them the documents. Since then this ****en credit bureau has never logged a dispute. When I call their call center they keep on telling me that they have want me send the supporting documents. I have resend the documents several time but when I call them they say they never received them. If this company does not want to help me they should let me know so that I will take this matter further. The last I had their response was that "this matter has been escalated"
