Internal transfer and missing funds as per Absa

I have an account with absa I dont even know for how long. I made a payment from my savings account to my credit card that has expired on the 15/09 and I discovered when I wanted to do the flight booking that I have paid to the wrong card. I emailed absa as I am outside SA to inform them they promised me that the amount transferred will be directed automatically to my current credit card within 48 hours and I waited as it was also appearing on my expired card. 48 hours lapsed when i checked there was no amount in my credit card and it was no longer appearing in my expired card I send them another email they responded and now told me they are going to investigate missing funds....Mind you this transaction happened internally to internal accounts no external accounts, secondly I am now stuck and cant move cos I don't have money to book for flights as I have informed them on the ,mail the urgency of this request they haven't even tried to contact me no nothing and I have sent them numerous emails either I get automatic response or that they have sent my query for investigation. So where was 48 hours coming from? and now where is the money missing? i should have understood if it was from an external bank and now i have to be stuck here without my will as they dont see any sense of urgency in all this. I am very disappointed in Absa service and its not for the first time I am getting the bad service from there. and they keep closing my case without myself being assisted
