NRB accting subscriptio

My wife has been getting an NRB nrb accting subscription fee deduction since March of R 156. <br> We went into the bank to get this sorted. Were advised someone would get back to us - never heard anything more.<br> Two weeks later noticed another debit on our account for March. Phoned about it and complained. Were told someone would get back to us - still waiting.<br> Suddenly 1 debit has been reversed. Why not both - and why the poor feedback?<br> Plus the account went into arears because of this debit - will the account be flagged as being poorly managed as a result? How does one deal with a faceless bank that does not communicate? And costs? And interest?
