Vodacom has no customer etiquette and no resolution to offer - they are part of the problem, not the solution

I'm still waiting for Vodacom and Vodacom Sunninghill (MT) to resolve my query regarding the cancellation of my dads cell phone number, which is part of my mom's estate. Vodacom kept sending messages to my mom's cell phone (the deceased) instead of my phone - after sending the death certificate and signing documents to take over payments. No attempt has been made to resolve the query. The social team only phone me regarding these complaints on Hellopeter, but no resolution for the past 8 months. Do you think Vodacom cares about their customers?
