Vodacom contract application is terrible

I have been trying to apply for a new contract with Vodacom, but their online application process is terrible and does not work. Fine, they'll call me back. The first time I could hear the person over the line at all, I was told that she'd call back. Since then I have tried a number of times further to apply to no avail, the online process is still terrible. However now when I answer calls from then the person at the other end ends the call just as I answer, then I get snooty messages of them having tried to contact me a number of times and that I should call them back. Does Vodacom not care for my business? Why are calls ended as soon as one answers? I am still prepared to apply for the contract, however the consultants must not end calls. I had this experience again this morning, phone rings, I recognize the number, I answer, then I hear the call being ended.
