Ridiculous Charges

Standard Bank has ****med me on numerous occasions with their ridiculous bank charges on an account that was said to have R5 monthly charges, the thing is they charge any amount they feel like and I have had enough I can not even leave money on the account because when I come back that money will be gone, just last month they charged me R200 just for the sake of it, and worse they changed/limited my daily limits without my permission I don't know who they consulted with or who gave them permission to access my accountant I am very angry about that they invaded my account without my permission so what else are there doing to this account without my knowledge. I am not happy with the service from this bank and I will be closing this stupid bank account. I feel **** to and ****** by Standard Bank.
