We provide customer support services via the system message mechanism which is available on your TSOP account. You can read about this service in our Terms and Conditions document.
You can also read our "How To..." articles to resolve some installation or usage issues by yourself. We've also covered optimization issues in greater detail in last chapters of a respective product documentation.
If you still cannot fix the problem, please log in to your TSOP account and write a message selecting an appropriate topic or send us an email. We will queue your request and respond as soon as possible.
