VERY VERY BAD SERVICE FROM VODACOM

I purchased a Mac December last year. With that a K4201-z USB for my internet use. Yesterday I'v downloaded the latest software for my mac OS X Yosemite Version 10.10.2. I could not go onto the internet.I phoned Digicape and they said I must go to Malmesbury Vodacom and see if they can download the software for me. I got there the gentlemen were very helpful but clueless. He asked the older gentlemen behind a desk. He said sorry we cant help you, you need to go to a Vodacare. He was very rude and extremely unhelpful. I said to him I cannot get to a Vodacare based in Cape Town. I asked do you have the latest modems, NO he said we only get them end of Feb. I said can you help me download the software as I dont have internet access.(Had to ask someone now to handle this complaint). NO he said. I left. Phoned customer care, I ended up phoning 082155 Ambugile couldnt assist me as he s supervisor said sorry go to Vodacare. I am DISGUSTED.I am in Malmesbury, I am dependendt on internet for my work.I need to download antivirus regularly (different usb usage). I SIMPLY CANNOT DO MY WORK. I cannot get to a Vodacare !. If my Mac gets any viruses I will keep Vodacom responsable Assist asap!
