Refund / Overcharge (1 year overdue)

Good day<br> <br> I have been speaking to Thabo at Vodaworld Midrand (I took my contact at Vodaworld originally so have been talking to them directly)<br> The call centre says they do not have my actual contract and have to speak to the store directly but after numerous phone calls, there is still nothing happening.<br> <br> The STORY:<br> <br> I took 2 contracts at R 169pm in March 2013 (Samsung S3 Mini's). For one of the contracts I was charged normal at R 169pm. For the other contract I was charged R 169pm plus an additional R 75pm (on the statement it said device charge)<br> This went on for 8 months that i was charged this device charge for the 1 contract. I complained and I was told, yes there is a mistake and they will stop charging me for the device (as my contracts are R 169pm total each) and that they will refund me for the 8 months which I was charged for the device.<br> <br> From month 9 I was charged R 169pm on both contracts and that was fine but I have still not received the refund for the 8 months which I paid extra.<br> <br> I have been trying to get a refund for 1 yr now. My contract has even expired and still I am getting more stories<br> <br> Please have someone contact me and assist. <br> <br> Regards<br> P Rugdeo
