Bad Service

I have been trying since September 2021 to have my account cancelled alternatively transferred from my late father's name to mine. I have submitted my forms to over 7 people. No one assists. Vodacom has now blocked my business number which means I cannot use my business phone. I am a business owner and lose money on a daily basis. I have submitted various complaints. No one responds. I have also lodged a complaint with ICASA and are considering suing for damages.
