Extremely poor service

I am currently using my late mother's contract number she took in February 2016 because when she passed away in September 2016, my father submitted her death certificate and he had to continue making the payments until the contract expired end of February 2018.

My father notified Vodacom in February that he would continue or upgrade the contract and he want to stop the contract after it expires, and he submitted my mother's death certificate again for the cancellation of the contract.

February and March have passed and still deductions are made from my father for the contract. He has been on the phone everyday since Wednesday, 04 April to cancel the contract because Vodacom keeps on deducting the contract amount from him and every service consultant he speaks to just puts him through to the next and no one can help to stop the contract.

It's funny how easily someone's contract is activated but a complete pain to stop the contract. This is extremely poor service that a simple instruction as to stop a cellphone contract can't be exercised.
