Polmed deducted more than double debitorder amount

On 2nd Feb I noticed that Polmed deducted R2700 from my account, although my debit order is only for R1200. When I phoned them, they read out an email, stating that there had been a fault on the system, and most members had been paid back, but some members can not be paid back until the 15th of February. I am very sorry, the fault on the system is not my concern, I want my money by the latest 3 February 2016. Taking someones money without consent, is THEFT!!! I dont care about system issues, I just want my money by tomorrow 3 Feb 2016!!!! How can they take money from me, and expect from me to be happy with the ideal of only getting it back on the 15th. When I own them money and dont pay, they just stop my benefits, but when they owe me, I must just wait. NO, I am sorry, I want my money tomorrow!!!!!
