Pathetic terrible service at fnb

Last Fri the 30th June I called the fnb call centre and asked a consultant to shift money from my budget in my credit card to my straight.. I requested R4000 to be shifted. And I had a total of R6688 in the budget. After she did it I noticed only R1000 was reflecting into my straight. And the balance in my budget was R2688. When I called back and spoke to several consultants at fnb no seemed to know what happened to my R3000 missing. I finally manged to speak to a consultant who log a ticked and advised I would receive feedback after 24hours. On Mon I called again and spoke to several consultants once again and no seems to know where the R3000 went. I have spent over R300 airtime been transfered to dep to dep as no one seemed to know what's going on. I contacted the online chat yesterday as well and was told another ticket is logged as the matter is still not resolved. I called today the 5th July and again spoke to tons of rude agents who kept cutting the call or not speaking on the call and still the issue us not resolved. The email I received with the straight balance is not corresponding with the amount that is in the account. I just need to know where the money went is R3000 is a big amount..
