Why is it my fault?

Upgraded mine and my husband's phone on line. Inputted the delivery address (which is, incidentally the same address as on our billing), a week later Ram sent an email saying they were delivering to a totally different address - essentially the complex next door to ours, but since they had the street address wrong, would probably not have found it anyway. It's apparently my fault because I did this on line and according to the person I spoke to, I put the wrong address in (really?? I deliberately gave them the wrong address?) To try and rectify this I spent 20 minutes on the phone to Ram, who then told me to contact Vodacom, who, when they weren't telling me it was my fault, took down the correct address (the one in their records already), but now I have to wait for the back office to phone to verify the address (the one I originally inputted and the one that is on their system - that one(!)) and if I don't answer the phone, then I won't get my new phone anytime soon - and somehow this delay is all my fault No-one is going to do anything to get the phones delivered with any urgency. Absolutely appalling service...
