Typed in wrong nick name for the quest Hello, leon. You will have to contact support at https://gamekit.com/faq/ or wait for a response from the support link you have listed. You will not get a response from tasks@gamekit.com as it is only a task checking email and it is not used by support. You will also have to be patient as it can take 5 business days for a response.
Future missions.and mission 2. Hello, torpedo678. If the 72 hours have passed, you will have to contact support at https://gamekit.com/faq/ to see if they can manually verify your task. This is rare though. Also, as this is an automatic task, you can pass the objective and even complete another one without it causing any issues.
Time for mission Hello, Laetitia. There is no way to extend the time for your task. Unfortunately, you will either have to finish it on time or you will not be able to get rewarded for completing the task. Please note that even if the task 6 timer runs out, there should be a new timer for task 7.
