Missing Money Transferred

A payment was made from Absa to my Standard Bank account on 28/2/2018 via eft. An Immediate Payment was done form ABSA to my daughters Standard Bank account. After 4 days the monies is still not reflecting in her account. After numerous calls to ABSA and Standard Bank nobody is able to assist us in this regard-this is really unacceptable, how is it possible that money can disappear from one bank to another and nobody is able to assist us with regard to this issue. My daughter has visited Standard bank branch and opened an inquiry with service request no ********** 932. Up to date Standard bank has made no effort to assist, stating that the issue is with ABSA bank. If Standard bank is so *********** how can we trust them with our money.
