Account Manager completely unresponsive

My company has been using Miro for years and have been bounced around to a dozen different account managers. The only commonality seems to be that they are all unresponsive. The only time I get a response to an email is when the account manager replies with “I’m not longer your account manager” and cc’s someone new. But that new manager never responds to the question. 

I’m on month two of trying to get a questions answered about migrating our data to a domestic server with no substantial response. Has anyone had success through a different avenue?
