Is somebody out there???

Dear Standard Bank, on 15 June I send an e-mail to your Prestige Bank Division to cancel a R15 Postal statement fee which I never authorised you to deduct from my account in the 1st place. I manage my banking affairs on Internet. I received no response so I understood it was done. On the 25th of June you deducted it again? When I followed up via e-mail after the transaction went through again in spite of my request to cancel this they informed me they are unable to reverse transactions and they will make an appointment for me with a Banker. This will cost me more than R15 to get to the bank, pay for parking and sit and wait for how long to get a transaction reversed that I NEVER AUTHORISED in the 1st place. I indicated this to the Prestige line and again total silence. I do not know who my banker is so please can I ask that somebody with authority reverse the transaction. This is not about the money it is about the principle of the matter. I have already send 3 e-mails about the matter, begged for help on Facebook to no avail so now let's see if somebody will assist. My request is simple. I just want you to reverse the R15 fee that should not have been deducted from my account. Thank you.
