Terrible customer service and creating expectation

I have been trying to cancel my contract prematurely. I have made the payment 27 November at 12:57 and was told by the lady in store to call after 2 hours and cancel my contract. I have done so and was promised it would be cancelled however, to date, nothing has been done. Today, 04.12.2018, I have called vodacom 9 times and still have no joy in canceling my contract.

I get told the system is offline or they cannot do the cancelation.

I have spoke to a nonhlahla, portia at 8am which promised it would be done after 1 hour and still at 15:39 nothing has been cancelled. I have also spoken to a lungelo which made empty promises, zakeli which had an attitude and told maybe its because I'm frustrated hence nothing has been cancelled as yet, who even says that to a customer???

I also spoke to a Lindani, whom eventually had me on the line for 22 minutes stating my contract would be cancelled but I would lose all my airtime and data!!! Seriously!!! Well my line just got cut by him and still I'm left in the dark.

I cannot remember the other names of the agent but extremely terrible service from vodacom and is the reason for my cancellation.
