poor customer service

I did my upgrade at the Vodashop online. Received my new cell and sim card. On the 29th of February 2016, I could not make any calls or go on to the internet. I used my wife's phone to call customer care .I was told to put in my new sim as my old sim was deactivated. Switch off my phone and wait 3hours. 4hours later phone still not working. After nine calls to customer care including a conversation with a supervisor. A visit to the vodashop., including two calls to the vodashop. A call to the technician. Four days later. My cell is still not working and no one from Vodacom has bothered to call me back as they said the would. This is extreme poor service, as I am paying for a service.
