How long until I can reasonably expect a response from customer services??

Is support@zoho.com an oxymoron?  How long is reasonable for customers to wait for response - can you give me an indicative time wait for help?

As a new customer I wonder if you can tell me what timeline I can expect for the query below to be answered by the support function.
At the moment I am stuck with being unable to use the service I've paid for until its connected to my domain.
