*********** Agent Not Listening

I've sent a paid up letter to ITC to update my record, They then sent me an email below.<br> <br> Kindly be advised that 60 days for the Marvin Finance account to be updated has not yet lapsed as per attached proof of payment the account was settled 28 November 2015.<br> <br> When i called into the call centre i explained to the agent that the company will not update on there side as they are a small time company and i cannot wait 60 days for a dispute.<br> She would not listen to me and just kept going on about 60 days - In very rude manner, which made me frustrated.<br> <br> In the past Transunion updated my things within 2 days...Im at my wits end and not sure what to do.<br>
