ATM errors and long investigations

I have 2 Paycards issued to me by my employer. I attempted to draw money on one from a ATM and a slip was given with error 99. I tried the other card and the same thing, slip reading Transaction cancelled error 99. Both amounts were taken from the balance. Paymentology investigated for 2 weeks and now they say its escalated over to Standard Bank and going in for a 3rd week. 3 weeks of not being able to pay casual labours. How is it possible that with other banks money is back in the account in 24 to 48hrs if the ATM has a error but Standard Bank takes weeks?? I mean if your technology is so poor that it cant record errors caused atleast go and ask the damn mall for the camera footage and see that at that time of withdrawl no money was received.
