Discover Credit Card Complaint

Discover Credit card department,

Maryland

Discover Card has inaccurately reported to -, -, and - Credit agencies that I had a late credit card payment -/-/2016. This is not accurate. After speaking with Discover card on multiple occasion they informed me on those multiple occasions that I do not have any late payments. When I contacted Discover they have informed me they have sent multiple off-cycle updates to the Credit Reporting Agencies to update the inaccurate information. This has not occurred as the same late payment is still on my credit reports. I have disputed the late payments multiple times and nothing on the reports has changed. Either Discover Card is not responding to the disputes or they are providing the same inaccurate information when they receive the disputes. All said the issue is not resolved and its been 3 months since the initial dispute was filed and Discover was contacted about the issue. I do not want to have to resort to legal means to get the issue resolved but will if it is not. This is black and white, I do not have a late payment in -/-/- yet they are reporting it late. This is a complete violation of the Fair Credit Reporting Act which is a violation of the law. This issue needs to be resolved ASAP.
