4 Days waiting for a Payment Link

So last month my bank card expired, and obviously been on a monthly superflex subscription, the payment did not go off. It is such a mission to rectify this. I have called 135 on numerous occasions, and getting empty promises of send a 'payment link' to rectify this card payment. Well, till now I've received absolutely nothing. Don't get me wrong, your call centre agents are doing their jobs, but it seems the back office isn't. I've received numerous REQ numbers, agents mention my query has been escalated to their superiors, but no emails or responses have been received. The key to customer care is communication which you are lacking. I can honestly say, I logged a call with vodacom for our home internet, and within 48 hours their technical department called to inform me that they are rectifying the problem. When will you get with the program?
