Incorrect billing and misleading data usage sms's

My contract with Vodacom was due to end Feb26. With that contract I added a 500mb data bundle subscription. So I phoned Vodacom on 15 Jan to discontinue further service after contract expiry date. However, when phoning the Vodacom cancelation dept., I was persuaded to continue with a top-up subscription (uChoose Flexi) and thus asked the consultant to also cancel the 500mb data bundle. On 1 Feb I received my account on which the data bundle was still billed without evidence of receiving that data, but the debit order at the end of Feb was for the full invoice amount including that 500mb data subscription that I had asked to cancel on 15 Jan. I had phoned Vodacom several times and every time they were \sorry about the inconvenience and that they are not authorised to help me\" then redirecting the call to another consultant in another dept. saying the same.<br> <br> During my contract my contract went over limit during some months and when asked to cap my account to the data and airtime I have, they said I have to pay for it.<br> <br> I gave up to sort it with them directly, because Vodacom doesn't even respond to my vodacom-survey-complaints nor to my complaints to consultants..."
