My account is wiped and I'm unable to email support despite being billed yesterday?

I need some troubleshooting help! Today I logged into our Klaviyo account and although all of our profiles are still visible, many feature seem to be deleted (Lists, past campaign history, templates etc.). I was billed yesterday for 1.5k active profiles, 15k emails. But even our payment history is wiped (I received an email invoice and receipt, but there is no statement of it, or any past payments in our payment history)

I went to email support and am getting the message that "Your access to email support and live chat has expired.Check out plans for pricing and upgrade options."

I'm mostly just looking for a way to contact support without having to pay for another upgrade, and hoping that all of our data isn't deleted?

Any help is appreciated! I'm just a non-tech savvy small business owner who is doing it all themselves so many this is just a huge oversight and easy fix on my end?
