Hi @RobinHaiSoft,
I split your question into a new thread since it's a unique topic unrelated to the one you were replying to initially.
Please refer to this thread: Trial Rate Limit Adjustment Request Form
The most important thing is to very carefully respond to all of the questions asked. Often folks will not include all of the information requested and due to the volume of requests & the staff allocated to responding we can't follow-up if the request is incomplete and it is silently dropped.
Hope that helps, please let me know if you have additional questions!
