I have installed Polyclinic wordpress theme in localhost under wordpress-4.4.2 . But unfortunately RTL support is not working. When i click RTL link in menu it is still showing page in LTR.
Also is there any way i can get HTML version of this template too? Because i want to develop the website without wordpress.
What do you mean by "click RTL link in menu". If you installed a theme demo content, the menu link only works for theme demo website and is to illustrate the RTL capability of the theme only. To use the theme in RTL layout you need to have your WordPress in RTL too. Please set up your WordPress to your (RTL) language and it should work just fine.
As for HTML version, sorry, I don't provide such files simply because I don't have them. I code directly to WordPress.
Finally, I strongly suggest updating your WordPress to newer version (4.7.4 as of current).

Although the mistaken purchase is not a reason for granting a refund as the theme does not mention it contains HTML template anywhere in the theme description (please see https://themeforest.net/page/customer_refund_policy#not-refundable), I am granting you the refund as a good will.
Good luck with your search for the correct theme. A tip for you: please don't use "WordPress" category at ThemeForest if you are looking for HTML template. Rather use the "HTML" category instead.
