It might be that, for some reason, someone may want to cancel the task in favour of a cash payment. However, we highly recommend against this, and we suggest keeping all activity on this platform as this favour could relate to fraudulent activity.
Once a task is completed on the platform, we can provide a secure payment method and help from a support team if needed. Once a task is cancelled, the services are no longer eligible for their work.
You can always respectfully decline and respond that you would prefer to continue using Taskhelper if someone does offer you a cash deal.
