Still no resolution

I've had an Issue with my Ipad not picking up the sim card/ connecting to the network for about 3 months now. Going on month 4. I pay them every month for services NOT rendered. basically they OWE me a refund. I went to the Vodashop In Killarney and they told me It Is a sim reader error and I need to take It to Vodaworld. I brought it nto Vodaworld on 30Jan2015. I was sent to your repair centre where a technician told me I needed to take my Ipad to the Istore across from the Vodashop In Vodaworld. I did that. The technician there told me to get It reported to Insurance as they can do nothing to fix It. I then stood In a queue waiting for an Insurance consultant to help me. My ticket number was C007 and I was assisted by a Shelley Whittaker. I filled In insurance claim forms as I am insured by Vodacom, signed the documents and we wiped my device. She told me someone would call me on that day to come and fetch this device for repairs or replacement. <br> it has been escalated they said. however to this day I STILL have no response or resolution. I want a refund and them to CANCEL my contract since i get no service<br>
