TransUnion support is non-existent

I have been making use of TransUnion for years, to track my credit profile, as well as their car value report product. While I find the products they offer very useful, their customer portal (MyTransunion) is just about unusable. And then, getting through to customer service is nearly impossible. The contact form on their website does not work, emails go unanswered, you need to wade through minutes of options to get to speak to an agent on the phone, and in many cases, the agents are unable to assists. I am unable to login with my cellphone due to an incorrect number captured somewhere. I also cannot change my number on my profile, as the site does not allow this. When I attempt to contact their support on the application, the form keeps on telling me that I need to completed all fields (even though it has been completed). I really seems as if TransUnion does not care about individual clients at all.
