No Support since ONE Week for even very urgent issues

4 years ago when I first opened my account on digitalocean, our company emails had a different domain name. Months ago we no longer needed that domain and changed our email addresses to new domain name. Unfortunately, since there was no way at that time to transfer droplets with the same IP address to another account, I kept the previous account in DO and continued our service to our customers within that account to keep the IP address of our droplets. That IP address was used with thousands of devices connected for our company’s iot service. Unfortunately, last week today, the devices stopped sending data to server, and we figured out that the droplet somehow went down. We checked that we made all the payments accordingly. Unfortunately, we can no longer access to our DO account associated with email address using expired domain and opened a ticket on DO. Since the droplet is down, we no longer continue to serve our customers with our service. I have mentioned this urgent issue but no one in support team seems to care and tackle the issue. They asked me to send passport copies, documents related with company and some other documents. I have provided those information and documents accordingly, but still no update. This morning it has been ONE WEEK since no resolution. I guess for serious businesses this is unacceptable. We are loosing money and customers but DO support team does not care at all.
