leaving me with no salary

Standard bank took 80% of my salary for the second month in a row. I have an outstanding balance on my credit card as well as my bluebean card. I have been unemployed for 13months. I started to work in the middle of March and received a salary of R3900 at the end of March. Standard bank took R2498 of that salary without any notice beforehand. This month I received a salary of R7200. Standard bank took R5729 leaving me with R1450. This AFTER I made an arrangement with NDS attorneys to pay an amount of R500 monthly on the card. I phoned them to ask that they return my money and only take the arrangement amount as I am now left with R1450 to pay petrol AND pay my other debt arrangements, which means that my arrangement on my Standard bank rcp loan will NOT be kept due to Standard card division who hands your account to debt collectors to make arrangements and then go and take 80% of your monthly salary. Why do we bother to make arrangements?? Just so that a financial institution can RUIN you?? So... the loan department can go to the credit department and request the arrangement amount from them as they are sitting with my salary. I will also forward Standard bank's details to my childrens school in order for them to collect the school fees as Standard bank card collections is sitting with my salary. The R1450 they left me will not be enough for my petrol expenses for the month so standard bank WILL be the reason for a job lost!! Well done Standard bank!! You do know how to kick your clients while they are already down!! And this just when someone are slowly but surely trying to get on their feet again..
