AWS Customer Support is Dismal and Unhelpful

I used to be an advocate of AWS. They have recently introduced multi-factor authentification and I have been shut out of my account. I have spent R1.5m on a project that will die unless I can get access to my account, but their help and customer service has proven to be dismal and unhelpful. I just hope this gets a competent human to contact me, with something other than a long email filled with jargon and unintelligible instructions.
