If you mean to say that you purchased multiple domains and wish to host them in a single hosting account at VodaHost, then that is entirely possible, and you are encouraged to do so .... there is no restrictions on how many domains you may host or websites you can create for a single VodaHost Hosting Account.
If, however, you mean that you actually purchased multiple Hosting Accounts from VodaHost, if it has not yet been 30 days from the initial day of purchase, you may request from Support that one or more simply be cancelled and refunded. You can then make the proper DNS (Nameserver) entries for each of your domains to your single hosting account at VodaHost.
