Charges after cancellation

I cancelled my transunion subscription in September (with emails to prove it) but to date, I am still being debited. I called Transunion in November and once again requested to cancel. The agent confirmed this was done yet I was still debited. I called once more only to be told that even though I cancelled , I was meant to call back and check (which is nonsense as once cancelled, it should stay cancelled ). I requested a refund from September and nothing has been done to date. I was told that a consultant would call me back and there has been no communication since . I find this so disturbing that someone like Transunion would continuously incorrectly debit a customers account after numerous cancellation requests and then not have the decency to refund me. What is more scary is that this could carry on forever and they don't give a damn
