Standard bank bizlaunch you have ****** and taken monies *******ly

I have a biz launch standard bank account for small businesses. Suddenly over night they have taken over R2000 off my account with a few reversals, 25 lines of transactions on my account which I was not notified of, and cannot budget for it, I pay monthly management fee of the account and suddenly there are extra costs that they have not charged and in one night have charged for 6 months or so, surely this is *******, no documentation on the claim of my money, no explanation of what the money is for, this is ******* banking practice! I want a refund of all the money take. From me and proper payment arrangement should be made once a detailed description of the amounts are made! You have ****** me and ****** from me!
