***** case unresolved

I have logged a ***** case that occurred on my account in March, no one has gotten back to me, everyone i speak to keeps giving me a few days then when i call no one picks up or my query keeps getting escalated, how long is this bad service going to last for before i have to go to the ombudsman? Im fed up at the fact that no one is updating me on the matter after promising to call me back, this is very appauling coming from FNB, you are starting to provide services the level or a start up company, someone needs to call me ASAP
