Please note that while I understand your frustration there, our response time can be up to 72 hours, even though we are generally much much faster than that. However in this case, you are actually asking for support on a product you havent purchased from ourselves. If the issue is only happening on that 3rd party theme, you would need to contact the author of that theme for assistance.
You say disabling the theme does nothing much for your site. What do you mean there? Are you saying you are still having the same issue?
With regard your question on support, you would indeed be asked to disable 3rd party items at times, including theme, if you are having an issue, and that should indeed be your first step. Note, this isnt just on our software, but pretty much any on the market.
