Confidentiality of bank details broken

My Sassa money is now declined for 2 months in a row. According to Sassa I received income out of another source. The average money I paid into my bank account was on average r700 per month. What is the use to have a bank account. What about the poppy law and disclaimer of confidentiality on bank details. No where in Sassa requirements it said that I not allowed to get more than R625 in my bank account. this is cash paid into the account and not not an income from one or other source. I got beneficiary to pay and it is easier to pay it through my bank account. This is not acceptable that your confidentiality with the bank is been broken to a third party. Please get this sorted out.bon the sassa conditions it said that the information will be confirmed on application and not on a monthly basis.
