Unhelpful Vodacom Services

My contract ended with Vodacom in December 2014, I proceeded to try and do an upgrade. My first two attempts in December due to incompetency on the sales agents side at (carnival mall, benoni) and on the online store.<br> In January i finally had done my upgrade only to now find out that instead of upgrading me, they took out a separate contract for me, and i am now paying for both instead of one. I have called the the customer service and was told that i need to speak to the cancellation department who i have not being able to get hold of for days. Today i was told i need to speak to the online store, where i was very rudely told that i didn't do an upgrade even though i clicked the upgrade button and spoke to a consultant where i did a sim swop as well. I would just like to cancel my extra line and receive my refund for the 2 months that i have being paying and not receiving the benefits.<br>
