Transunion playing hide and seek

I have tried to get the bureau to update my credit information - I tried to upload information via their website bu the systems keeps failing and giving me error reports. I tried to send an email to Transunion but received an automated response that they no longer accommodate e-mail submissions of disputes, queries or general information. And that if I want to register any new disputes and/or queries or obtain information, I should call the Consumer Contact Centre on ***for assistance. But when I try to call the consumer contact centre the call centre is automated and in no ways allows for the logging of new disputes.

I find this extremely nerve wrecking because how else am I supposed to get my credit information updated?
