NO SERVICE. INCORRECT DEDUCTION

I wanted to cancel and disconnect my services. The app would not allow me to do this, after trying several times even with an option on the App to do so. I then sent a DM and an email. Your staff could not understand what I was asking. I am not using the service from the start of December so why must I pay for a service I am not using , with the lack of communication from your side my usual monthly fee has now been deducted and now I am told their is a cancellation fee, that is *******. I am NOT happy!!
