No way to contact Transunion

I'm trying to access my account and I get this error:--

"Your account has been locked as there have been multiple failed attempts. Kindly contact us, during office hours, on ***for assistance."

I'm deaf, so cannot use the telephone. Your website offers no email addresses, only a snail mail address. Are you not aware that this is the 21st century? If you're this ***********, how can you be trusted with prople's data?
