Never-ending circle of Twitter “support”

Can someone please offer advice? I created a Twitter account a few months ago for my organization and linked my mobile phone to it. But we had email issues so I created a new email address. But now I can’t remember the password to our Twitter account or the email address that was used to create it.

I’ve sent in multiple help queries from my work email, but I keep getting automated replies telling me to log-in so that I can get support – something I’m unable to do. And, to make matters worse, creating a new account won't work because the phone is linked to the old one.

Does anyone have advice? Or an email address/phone number that can be used to contact an actual person at Twitter?
