I have an outstanding support ticket with Cryptopia that has been open for months with absolutely no response, not even an email confirmation of a ticket created. I basically need to recover an account and think that if I ever do manage to recover that account the only thing I'll do with it is remove the assets and be done with the site. I consider ignoring of support tickets to be unacceptable customer service. I had a similar situation that I needed BitTrex' help with and they got back to me and resolved my issue within hours of me having provided the information they needed.
I have a similar situation with SpectroCoin and they've basically told me there is no way to resolve my issue, but at least they responded.
My problem is that I with no warning lost access to my log in email address. On *most* ordinary sites if that happens you simply log into your profile page and change it and that's it. But with some of these crypto trading sites, Cryptopia and SpectroCoin included, there is no way to do that. If you lose access to your email address, you just lost all your funds. I had no idea an email address was such a point of failure. BitTrex has a process for changing your email address and their support is responsive. Poloniex says there is no way to change it, and fortunately in that case I'd activated 2FA only confirmation for withdrawals, plus I don't have anything significant on there, so I'll just create a new account.
So a warning: don't trade on Cryptopia. They stink. Any of these other sites, only use an email address from a service that is not likely to go out of business--gmail, yahoo, msn, something like that. If you are using an email address that might go away at some point, then go through whatever you need to do to change to a more reliable one while you still have access to it.
