NO REFUND AND NO SERVICE

I have been battling with my new contract since I ordered it. First I received the incorrect sim card with the phone and was billed for it and then waited a week for my new sim and then was billed for that as well. (My sim was ported from MTN to Vodacom). They advised that I will be refunded. This was logged 12/02/2015 and should've received my refund 26/02/2015. I called in and complained and they escalated the matter. Yesterday when I followed up again, I was told that I have to wait another 14 days!!! Really!!!! <br> Then another problem occurred, when I eventually got into my Vodacom App on my phone which had problems connecting, I realised that I was placed on the incorrect contract. The consultant then sent me a migration quote and it was all fine and I will move over to the initial contract in a months time, HOWEVER, I had queries and tried to get hold of the person for 2 days now and there is just no answer on the phones, emails and online chats. It is driving me insane. How can you run a business like this and there is just no way of getting hold of a person. Even the more senior people that I have emailed does not bother to respond to return my calls.
