Your hosting account can be cancelled at any time however the 30 day money back guarantee is only valid for the first 30 days. After that period, you would not be refunded your hosting fee if you decided to change hosting provider.
If you purchased a domain name from us with the hosting package the domain part of your order is not refundable, this is due to the fact that domains cannot be unregistered.
