Bad Service

I have a student account with standard bank that I no longer use , the account has been debited with ********** debit orders , and since it was not being used no funds were in the account , and as a result the debits were being declined and I have been incurring bank charges for debit orders that are not mine , I called the call center numerous times and was told that they cant block the debit orders indefinitely they can only do it on a specific day , I then went into a branch and told them that I am disputing the bank charges but was told there is nothing they can do . I have been receiving text messages that I must call the collection center and make an arrangement to pay of the bank charges as the account is in arrears , I called and explained what has been going on and the agent said I should go into the branch and sign a dispute form . This morning I woke up and went into the branch , explained my story and was told that they cant do anything the debit orders will continue going off my account , they cant stop them nor freeze the account , I will continue incurring charges and I have no choice but to pay the amount in arrears and debits will continue , the consultant was rude and unfriendly , her name was Keamorata Sejake , she did not even try to assist or give me solutions , this was at sanridge in Midrand , I am very frustrated , and not happy with this matter.
