I want my money back

On the 20th July 2015, I setup a debit order facility on the DSTV self service portal as I have been paying for my service via EFT. I then called then on the 23rd to find out if my debit order would go through on the 25th and was told it would go through. On the 25th I received a message via my decoder that I need to make a payment. I then paid R845 via EFT. On the evening of the 26th I received another message via my decoder that my account is suspended for non-payment. I thought this was odd because when I called on the morning of the 26th, I was informed that my outstanding balance is R0.00. Anyway, I proceeded to pay more money via the DSTV self service portal. I paid R829 + R63. My account was then activated. I called on Monday, 27th requesting a refund of the extra amount that I paid and was told I would have to wait 30 days. I find this unacceptable and disgusting. I want my money back within 7 days. Why must I wait 30 days especially knowing that a debit order will go through on the 25th August again? I want my money back!!!!
