Poor Client Service

I called in early last month in April , a few days before my debit date to cancel my Tracker device, the lady I spoke with said my account will be debited for the last time then cancel. Last week I received an email saying I am owing R165, I called in on Monday the 16/05/2022 to ask what the R165 was for and spoke to Oscar Shisingi who told that it’s an amount I am suppose to pay in order for my agreement to be cancelled which I immediately paid. Today I called in for a cancellation letter to show that my agreement has been cancelled only to be told that the request for cancellation was never logged. I am greatly displeased because I need that letter urgently to submit for my liability assessment.
