Almost a year later after I canceled NetstarGo and they still debiting my account for the rewards programme!

Cancelled NetstarGo one year ago and they still debiting my account!!! Absolutely terrible service from this ******* service provider. I called the call Centre to cancel NetstarGo which is the rewards programme on 23rd November 2023. I received a message in March 2024 to follow up with me if I still want to cancel and till today they still sending me dumb followup messages to ask me if I want to cancel yet they still have not processed my cancelation a year later and still debiting my account!! Please don't use netstar. It's a *** service provider.
