Pricelock Mayhem

I ordered the Pricelock last month, it was approved and an sms was sent to say it would be delivered in 4/5 days, i called a week later (20th october) and was told it was delivered on the 12th meaning i was being billed from the 12th already for a decoder i havent received, i called the courier company and was told it was signed by an ashywhn whom i dont know and told them its not my fault they delivered to the incorrect address i want a new decoder the same day, a new decoder was delivered the 21st October and i called Multichoice to have the decoder activated just to find out they were activating the decoder that was delivered to the incorrect person. now i am being billed from the 12th and being billed for 2 decoders. i keep on calling back and still waiting for someone to call me back from Multichoice to have this sorted out.
