Well, then I wish you very good luck with your new theme.
Regarding the speed issue, Woffice is used by more than 4500 companies around the world and have been optimized since more than one year to be the fastest theme of its category due to many enhancements (requests optimizations, minified files, OOP code...). Your issue is most likely due to your server settings and/or the use of many greedy plugins. So, the is issue is also most likely to stay no matter what theme you are using.
Our support is always looking to help yet it can't work if you don't cooperate and you see support as "guy who will login my site and make everything better in 10s". Let me be honest here, those guys do not exist. We talk, we gather as many details as possible, we test with our customers and then we find a solution. If you are not convinced about that please have a look to the other ratings.
Yet, we cannot help we do not want to be helped or to participate. Also, the extending support is not a better support, it is a longer support. We reply to all our customers the same way no matter if they have extended support or not. If you are looking for a guy to make everything work for you, it is a freelancer ;)
Please, have a wonderful day.
