Horrid service

I have been calling, emailing from the 12/08 for a Agreement details copy for my old contract which I upgrade, i have been sent from pillar to post, no one knows what to do, I even sent a message to the social media team and still nothing, this is very frustrating. Im on a call with vodacom as I type this and no manager or team leader is prepared to take my call, PATHETIC to say the least
