Disheartening Service

I hold a data contract with Vodacom, I was behind on my monthly payments and made a telephonic arrangement with a consultant from Vodacom to have them deduct this payment from my account. The deduction was successful and my understanding was that their systems would update automatically, and when this didn't happen, I simply called in and was told that I need to allow 3 days TAT, which I was also happy to do since I was behind on payments anyway. When I called in on the 04 day - the consultant I spoke with was very rude, he disputed that I'd made payment arrangements and insisted that Vodacom did not take my money and this caused even further frustration. This is now the second week and I still have no resolution every time I call to inquire no one know's what's happening with my account. The level of service I have experienced is disheartening to say the least and I use this data for work and this is creating an even bigger frustration on my end as I am also trying to make a living for myself. This has been escalated to a team leader but still no resolution to the issue...
