Anyone having problems accessing their Mercury account?

Everyone at my company with access to the bank account is getting the following message when they try to log in:

It looks like you don’t currently have access to any Mercury accounts. If you believe this is a mistake, contact an account admin or email help@mercury.com.

And their help@ is replying with a form email:

"Our Customer Support team is currently receiving a higher volume of inquiries than usual. Please anticipate that general inquiries will receive a response within 2–3 business days..."

Is this a bug that a lot of people are experiencing? Does anyone know someone who can help quicker than 2-3 business days?
