concerned about my account

Hi Lewis this is not really a complaint but rather a reach for assistance as your call centre is not very helpful. I have the 3 months loan with you guys. My debit went off already yesterday, Now im expecting money to be transferred to my account on Friday and i am worried that you guys will double debit me as a result of you having a Naedo tracking switched on. How do i prevent this from Happening because i dont think it would be faire as a good client of yours for this to happen because its a long process to get my money back. I also cannot change my account number because this is my main account and the transfer is comping from my employer. Please urgently advise?
