Creative Accounting

Standard Bank is using creative accounting by switching my transfer from my money market account to my prestige plus account to the Monday from Sunday. Then Standard bank wants to charge me for using an overdraft which I did not. I used your cellphone app on my Iphone, on the Sunday to make the funds available before using the funds, the funds showed as available and my balance had the funds added. I as anyone would assumed the funds was there, but No SB says it only happened the Monday, No it did not, I did the transfer on the Sunday, your creative accounting is now taking my money for interest on a service I did not use!!! After being promised by the call center manager that the interest would be reversed, I am still waiting for the reversal. Please give me my money back, I did not use an overdraft service, so I should not have to pay for it, I transfered the money from my own standard bank money market account to my own standard bank prestige Plus account, and the app on the phone showed the funds as transfered. I did the same with much larger amount in the week you did not charge me for those, amounts more then 20 times and no interest charged, just because the bank as weekend!
