The customer service team at Sitewise are very friendly & helpful! They always respond quickly when I have questions or problems with my account which makes me feel valued as their client!! Nothing really so far but it's still early days :) We've had some issues recently where our site has been hacked/phished (which we think was by one person) - this caused us quite alot stress since there were many people visiting / using that domain before they got removed from ours etc., however once notified about these things via email response time can be quick if you're working through someone who knows what hes doing ;).
