New contract with Vodacom

I app**** for a sim only deal with Vodacom +-4 weeks back. I have subsequently called and spoken to over 10 people via online chat or call centre to assist me in getting a sim card! I was initially after 2 weeks sent the incorrect sim card after distinctly asking for a nano sim. I re-ordered the sim and now RAM has the incorrect address details for the delivery. They cannot change delivery details after calling them so I called Vodacom to change the details. I called RAM again and they still do not have the updated details! I try to speak to your online chat people and they tell me they will call back but never do!!! This is just shocking service for a new customer.
