Vodacom Double Billing

<p>For the past 4 months I have been billed twice each month for my device. I have reported it to Vodacom and they told me that that I will be refunded for the double billing. 5 days later I called contacted the call centre again and they told me it is still at the billing department and they should have contacted me. Another 4 days have passed and and they still didn't contact me. Few days ago I received my latest bill and the device is double billed again. The next debit order will still include the double billed device. I'm concidering the move to Cell C for them to buy out my contract. The voice and data charges are a lot cheaper.</p>
