For testing purpose you should have used a test domain instead of using your main domains. As the
Hyper-V VPS technology is new, you should have asked our techs to transfer the domains which would have surely avoided all the troubles you've gone through. We do provide name servers to all our VPS hosting clients. But the number of name servers which we have registered with enom has gone up drastically due to which we are facing problems registering the new name servers with enom. This is a temporary problem which will be sorted very soon.
You also have the option to use your own private name servers which would look more professional compared to our default name servers.
As this is a VPS issue so I've moved the thread to the right section.
