Double amount deducted from my account

i switched to debit order to pay my tv license and yesterday they deducted 318x2 for my tv license i had to pay the 318 as there were penalties since they could not get the money last year end October, i tried telling them over and over that some one from their side was doing something wrong as i kept getting a notification saying the debit order failed, so yesterday they took double the amount they were supposed to take and they are telling me that it will take 8 weeks for me to get back the money. seriously how can that be i need that money i have other debit orders to pay and now the SABC has taken all my money. there are a lot of people out who run away from paying their TV licenses and i am trying to do the right thing by paying and i get **********.
