Useless Vodacom Cancellation Department.

So I have been trying to cancel my contract with Vodacom. On Thursday 22 March I paid my premature cancellation. Then on Wednesday 28 March I call Vodacom cancellation department at 1pm and they say they see the payment they will log immediately a deactivation and it will be done in an hour. Every hour there of I was waiting for an sms to tell it was done and nothing. On 29 March I call Vodacom itself and I ask them they said they see the money but no log was put it. I must phone the team leader at Vodacom Cancellation. At 5pm I call and spoke to a team leader and he said the admin have left and he will call me between 9 and 10 on the 30th March and promised to sort me out. It is now 5:29 and still no one has called me. Can someone please just help me? Why can’t anyone do their job?
