Consumer Portfolio Services Bank Account Or Service Complaint

Consumer Portfolio Services Bank account or service department,

Other bank product/service Account opening, closing, or management Texas

I have noticed an inquiry on my credit report from Consumer Portfolio Services, CPS, I called the number provided asking them to remove the inquiry since I have never applied for a loan through them nor have I given them a permission to pull or check my credit, after few minutes of questions they assured me that it will be removed, it has been almost a year and nothing was done, I called a couple of weeks ago the same number & was told that they have no record that the inquiry was supposed to be removed but this time it will be taken care of ... .... I honestly do not trust these guys and need help with this issue. Thank you.
