Bad Service

I upgraded my contract and they sent me the wrong color, after numerous phone calls to asked when device will be picked, I got 3 different stories but eventually after 2 weeks it was picked up, another 2 weeks for reversal by then they deducted the payment and after again numerous calls later, they finally reversed it and have put me back on the old contract. My question is, why put me on the old contract when I don't have a device to use benefits and again I have to pay for services i can't used. I have asked to be pit back on the contract I upgraded to, but it no longer exist and I now have to pay more for it. As a vodacom client I am shocked for the kind of service I have received and me as the client is just paying for it.
