Being charged for no reason...on the hand banking with no card

This morning when I woke up I see that my account has been charged with MDS fee of R8.50 seven times. I call Nedbank to inquire and a lady called Buyelwa from Lifestyle Banking at Nedbank tells me that this is fees charged for debit orders. I told her that I don't have debit orders on the account in question. She told me that she will send me a form to request my funds to be returning, however only one R8.50 will be returned. Upon asking why should I go through this process, she still dwelt on debit order charges. I repeated my statement that I don't have any debit orders going through this account so I fail to understand why I'm being charged. Instead of answering me, she dropped the call in my ear . Second issue I have with Nedbank is that I ordered a card for my check account and everytime I go and collect my card, I'm told it's been returned. I have no card and if I want to transact, I have to transfer funds from one account to another. Using my phone to tap, money app does not allow for this. This is such an inconvenience. I am getting tired of the service I'm receiving from Nedbank.
