UNAUTHORISED DEBITS

For months (and possibly years) my father has had sums of money deducted off his bank account which he has no idea what it is for. it reads ACB DEBIT:EXTERNAL WFSDRORDER********************. Moreover there are a number of other debits which are not supposed to be there. Upon taking these on with the bank and arranging for these to be stopped with the bank - despite this , these still persist. My father is a pensioner and is supposed to be on Prospective package which supposedly carries no bank charges( yet he is being charged over R1000, moreover he's charged R150 to reverse these "debits". ABSA cannot be allowed to just deduct from your account without authorization from the Client? We've requested assistance on numerous occasions and gone to branches to instruct the bank NOT to grant authority to these transactions - yet they still persist and no-one at ABSA seems to have a straight answer. They don't seem to make protecting their Clients' money a priority. We still also have a ***** case open and have not had any joy since JULY. Several times we've called and have even had to go inside the bank to get them to call. The person who's been assigned the case has not had the courtesy to give us an update or provide feedback despite the banks commitment to resolve this within 14 days. The ***** department has been of no assistance whatsoever.
