fees charged twice

I was charged as usual on the 26th September the maintenance fee and a Saswitch fee which I am used to for as long as I have the account that on the 26th of every month all Saswitch and Maintenance fees are charged. I called since Yesterday to check why I was charged on the 06th October as well. Finally after many calls, I was advised by Antoinette who is the resolve Manager that they will reverse the maintenance fee and not the Saswitch fee but these were charged to me on the 26th September already so I am just supposed to accept that Nedbank will charge a Saswitch fee when they feel like and I am supposed to accept that. I will not accept that and Nedbank will reverse the full amount that they charged me on the 06th October
