Our company ZOZO Living - selling oversized vinyl wall decals online - hosts its website with Openhost under the global domain zozoliving.com. Yesterday, Sunday June 1st at 10am our domain was taken from the internet.
After several emails / phone calls we finally (at around 5pm) received an announcement from Openhost:

It is with regret that we advise customers that we are experiencing a major problem with our Domain Management partner, Enom.
For as yet unknown reasons Enom have disabled our account and changed the nameservers of an as yet unknown number of .com .net and .org websites.
We have made several calls to their US-based tech support but because it is outside of business hours they have refused to help and continue to tell us the only thing we can do is email their risk management department which reopens on Monday, US time. We have since been hung up on when making further reqests for help.
Enom are the second largest provider of Domain registration world-wide and we are perplexed as to why they have disabled our account without any notice, particularly over a weekend.
We can only apologise if this is causing you an inconvenience and assure you we have done all we can so far to get Enom to reinstate their account.


Has anyone had experience with similar issues?
Or does anyone have an idea how on earth this can happen? It seems pretty rude to me.
Has anyone suggestions on how to make sure this will not happen again?

We're pretty worried as because of this issue, which is totally beyond our control, we're losing (potential) customers.
Any advice/comment/suggestion is appreciated.
