Terrible customer service

Subscribed to quarterly billing in error. Immediately recognised my error but couldn't find a way to cancel or delete my account, so i contacted support asking for assistance to cancel. They promptly responded to say someone would soon be in touch to help, then went silent and unresponsive. Have subsequently found how to delete my account but no response on the refund. I haven't even used the site... Shocking customer service and terrible that they make it difficult to cancel your account.
