Vodacom, remember me?

I went online to [URL Removed] to purchase a once-off data bundle. After going through the entire transaction, I got the error message on their site that they were having technical problems (no surprise there) and that the purchase had not been provisioned. I logged out, back in, and tried again, but it gave me the same error. So i just left it. Only to find that I have been billed for two data bundle purchases on my account now. I have now spent two weeks on the phone with Vodacom to get this resolved, as I all I simply want is for one of the purchases to be reversed on my account. Do you think they are able to do this? Nope. All I keep getting told is that \our team is looking into it and we will contact you within 48 hours.\" Well, this is the longest 48 hours of my life, as I have not heard from anyone. Come on Vodacom, get it together, and do a simple reverse on a contract-holder's account. This is seriously not a huge ask. I expect this will be resolved today and that someone there, anyone, will actually communicate with me! "
