I then had to switch from my savings account to a cheque account, and funds were not being paid towards this account. I was then debitedan amount of over R800 for the seetlemenmt of this account. I am no longer receiving data on this, and have just been informed the contract has been cancelled.</p> <p>This morning I have been debited R453.97. I tried quering this, and I have been told this is the for “Debit Order Rejection Fee” of R136.35. where is the extra amount coming from??</p>
