Ok, i have subscribed my UniFi and subscribed one channels that is billed monthly (For survey Purposes)

Then now i would like to terminate the Monthly Billing Service, but seems like it is not possible to terminate it on the STB itself.

anyone has any ideas how to terminate it? i have went to TMpoint and they ask me terminate the VAS (Value Added Service) within the UniFi itself.

And after 1 month still same, UniFi Still Charges me
