Never again

I have been offered a new router and cell phone contract which I 1st accepted but then returned within the correct time frame. Then in August they deducted almost dubbel the amount and when I phoned they did not know the router and cellphone was returned. They said they will return the amount they deducted within 7 - 14 workings days after 21 days I phoned again and it was still not returned so I said I am going to reverse the payment ant just pay what I owe. Beginning this month they deduct more again because of penalties which is not my fault and they stil have not allocated someone to last month's problem. I am sick and tired of vodacom and will be looking for Telekom to buy me out
