Billing after contract cancelled/expired

<p>I made a call to Customer Care in May since my contract was to expire on 10 June. i wanted to cancel it. I went through the process and was told that my last debit date will be the end of May since my contract expires in June 10. i agreeed to this with the consultant. Now i have received a statement of billing for June and to my suprise, i called customer care again and they said this is how it should be. i asked for recordings of the first conversation where i was told i will not be billed for June. I made the call on the 07th of June and to date no one has come back to me. I see that it is Vodacom's plan to end up debiting the money before resloving my query. This is not on. now i have a reference number: S3-GXB3P-PRBYG</p>
