Voice bundle **** desktop site

Accessing the desktop site I signed in to purchase daily voice bundles. The bundle packageI chose was the 900 min 3mins a day package. I had purchased the same package before on my cellphone using my airtime but this time round I wanted to be sure that I didn't buy the voda-voda bundle. Online there is absolutely n o indication given with regards to it being exclusively voda-voda. I purchased the bundle only to receive a message that my soda to soda bundle has been recharged. I called an agent to report the matter saying that no indication was given that it was voda-voda when purchasing the bundle. She proceeded to say that she could not assist me if I had already paid. How is this my fault? I expect that Vodacom do something to amend their site so that they don't deceive people in the future. Make it explicitly clear that it's only "voda-voda'. It would be fair that they credit me with the money I spent in airtime at least.
