You can deactivate your radio station by going to the Billing section of your radio station. You can see this section only if you login with the owner's profile.
You will need to type the name of the station exactly as it is. The field is lower-upper character sensitive.
In case that you have issues with getting the name correctly, check if you have an extra space in the end of the name.
This is a common mistake. Otherwise, please send us a support ticket and we will be happy to assist you!
