Disgruntled customer _how long is your 72hrs!!

Vodacom I'm highly highly disappointed with your level of service. I've been your client for over 2 decades to only be treated like this. Since August 2021 when I made a request to cancel a data line that is no longer in usage & contract expired already . Up to now - no resolution on the matter ,instead i've been taken from pillar to post and empty promises that you will investigate and call back but no resolution. What must 1 really and I mean really do to get service !
