Dear Sirs
I have recently purchased two licenses from theme forest. However, both websites are extremely slow. I spoke to hosting provider Siteground but they said it is something to do with the theme. I would like you to take a look. If you cannot resolve the issue please kindly issue a full refund. I have emailed you a couple of times.
