Absolutely shocking customer support for simple payment collection issue

It's unfortunate that one can't give 0 stars. In September, my wife received a payment due notice from Vodacom for a contract that was paid by a (now) expired card. She duly went and paid the amount at a Vodacom store and updated the card details telephonically. A few days later she received a notification from Vodacom that they had escalated her overdue amount for non payment, despite having just paid it at the store that week.

I don't want to document here just how many calls she has made, how often she's been passed from pillar to post, getting hung up on by the phone system, recalling, working with people who cannot simply acknowledge her payment, for which she has a receipt. As I type she's on a call that she's been on for half an hour, being put on hold, having to call back and just getting no assistance whatsoever to resolve a simple issue. It's also incredible to me that a *phone* company has such terrible quality support phone lines, seemingly untrained staff, inefficient payment collection services, the list goes on. I'm appalled.

Honestly Vodacom, I left you years ago for similarly terrible service and it seems nothing has changed. My wife is almost ready to do the same, to one of your competitors. Well done for *****ing defeat from the jaws of victory.
