So typical Vodacom Service (non-service)

I contacted Vodacom on the 9th of September notifying them of my mom's death and told them to cancel my mom's contract. I was told this will be done with immediate effect and that the last debit order will go off her account on the 1st of October. I reiterated that she had a cellphone contract and data contract, and was told both will be cancelled. Well, as in true Vodacom style, they cancelled the cellphone but not the data. When I contacted them today I was told that I need to complete a form and send this through to Vodacom along with the death certificate. WHY WAS I NOT TOLD THIS A MONTH AGO?? So typical Vodacom service. Every time you phone, you get a different answer with different requirements. Can you please not just be consistent in your service!! Same requirements EVERY TIME!! I will not pay for another month's data as it was your service agents who do not know what they are doing!
