Trying to cancel my Rain 5G without any luck.

I canceled my Rain 5G with in August for the end of Aug, they still debited my account on the 1st of Sep and now on the 1st of Oct again, router was already collected from me in the middle of Sep, I logged a couple of calls now, and complained on the mybroadband forum on the 2nd of October whereby I was told that my case was escalated to the relevant department with reference number *** to follow up on if I ever wish, not sure what he means by follow up, because they do not have a place to follow up or respond to anything. Still waiting for someone to contact me. Why does it have to be so painful and hard to cancel a service. I do not know where I am going to get money for food and petrol, because they took my last money on the 1st.
