Worst service provider gets even worse, is it even possible

I am now truly convinced that Vodacom has completely lost its way, definitely the most *********** service provider. i have been with them for over a Decade, and after my last contract term it was really unpleasant how in a company as big as Vodacom they have not one person with the ability to load a new bank account on my contract like really? despite my contract ending and not being contacted for a new one. I went in store and cleared my balance and ended my contract , it was confirmed in store and despite not receiving a device or airtime the Vodacom proved to be even more *********** by not canceling it seems. I spoke to a lady from Vodacom in Febuary (might not be from Vodacom cause she seemed intelligent) who never contacted me back. I'm Now handed over????? Wow Vodacom with service like this i hope you don't last long.
