Shocking Customer Service

For two days I've tried to purchase the Apple iphone online special to no avail. I've completed the form several times, and I get a page that says an agent will call me shortly. I did receive a call but when i answered it, the call ended with a dial tone in my ear. Then a text message came through to tell me that Vodacom tried to phone me, but not to worry, I would get another call later that day. Well i didn't and nor did i get a call the following day. I've tried calling vodacom - I waited for 7 minutes.... I've tried to use the Contact Us Request A Callback button...all to no avail.

I can't do business without my phone - can I please get some better service??

It's made out as if the online system is so easy and seamless...

seeing as i don't have a cellphone you need to call me on either ********** 666 or ********** 523
