Where is the responsiveness promised? Everything is messed up!

Hi

Where is the responsiveness of this theme (and others)?
It’s claimed to be resposnive but just by testing the display via your demo and the options on top to have the different views will have on tablets, phone etc. it clearly show there is always something going wrong in the display

tabs and adresse in vertical smartphone display is messed up
comment tab and adress in horizontal smartphone display is messed up
comment tab in vertical tablet display is messed up
user comments, add listing button,sellers details, and contact author in horizontal tablet display is messed up

All that on your own demo site (verified on my tablet and smartphone too, still the same messed up display…

I upgrade from the version i had to this one because it was said to be responsive….
