Tyme banking

Who else experience this-my son app**** for sassa R370,it was approved in August-then in September until January it was decline-this is what Tyme banking do-you create you a voucher-then the minute it expire-the money goes back into your account, then you have to create a voucher again if you don't withdraw it in 30 minutes, so what does Tyme banking do-it shows now that you received another R370 on the statement and sassa now sassa see it as another income and declines your grant for the next few months.
