MultiChoice Does Not Care About Customers!

I traded my PVR for an Explora on 23 May. As there is only 1 channel I was advised by MultiChoice about a special for R849 including an Explora. I sent an SMS to DPP, after going through the entire application, the call cut off, I send a 2nd SMS & went through the application again, then told the system had frozen & that I would be called back. I started the process again with a 3rd SMS. I was told I had an outstanding balance, huh? They advised me of a Smartcard charge that should be refunded but that they couldn't help. I went to the Agency & after waiting an hour, was told that they hadn't charged me & I must contact MultiChoice. I paid the balance & wrote it off for my own sanity & activated my package on 8 Jul. I asked so many times during the process if I would be charged any pro-rata fees or double subscriptions. On 21 Jul my acc was debited with R1,870.46. I called 4 times, sent 3 mails before being called by Jabulani on 19 Aug. He proceeded to explain the charges to me, but he made no sense & I was more confused than ever. He GUARANTEED me that on 21 Aug, there would be no debit order as I was in credit. I swear as the sky is blue my acc was debited AGAIN today. Now what?
