Pathetic service delivery

Can I give a negative score for this? Here is the breakdown:

My contract was supposed to end the 27th of October 2020. * Called 7th of September to give notice of cancellation, consultant told be it was too early. * Called again 6th of October to cancel, consultant confirmed cancellation was logged. * Called again 14 December, since I kept receiving invoices, for larger amounts than my initial contract. Consultant informed me that the cancellation was not processed. Consultant confirmed that the cancellation was now logged. * Called again 12 January, once again I was told the contract was not cancelled. Consultant told me the contract will now be cancelled. * Phoned again on the 19th of January to sort out billing and contract still not being cancelled. * Phoned again on 6 February as the Consultants still could not manage to do their jobs. Contract was still not cancelled and the invoices kept coming. * Sim eventually got converted to prepaid en of February. Since then Vodacom kept telling me my billing issue is being escalated and that someone will need to listen to the recordings etc. to figure out where the issue slipped in * I called again today (7 April) only to find out that nothing has been done.

What the are you doing Vodacom?? Where is your customer care? Pride in business? Do you not train your people? And your advice to me is to pay the amount to prevent it affecting my ICT score and then dispute it. Absolutely not. You will not get a single sent that you are not owed. Your consultants messed up. Fix this.
