NO RESPONSE

I cancelled my service on 27/9/17 - went into the Rosebank branch, filled out a form which they sent to the cancellations department. On 9/10/17 I received an invoice. I emailed the cancellation department and asked for an update - no reply. I went into the Rosebank branch and they phoned the cancellations department who told me the cancellation will take 21 working days. By my calculations, the 21 working days is 25 October. I then AGAIN received an invoice dated 9/11/17. I contacted the cancellation department again via email on 13/11/17 - no response. I then registered a complaint via the website on 15/11/17 - NO REPONSE.
