Overcharged, no refund and no feedback on cancellation

<p>Vodacom over-charged for a phone that i did not buy from them. I am still waiting for my refund and it has been more than 4 weeks since i reported this to them. They said it would take a week to get my refund done, but this has been longer. If i had been the one who had underpaid my subscription my phone would have been locked in 24 hrs but when they overcharge they say it's ok for them to take however long they want to pay you back!! this is BS service!! I have been trying to cancel the contract and i still havent received confirmation.</p> <p>The statement for this month also indicates that i will be overcharged again!! Can you just cancel the contract, your service is really poor!!@</p> <p> </p>
