Terrible service

Logged a ***** case with discovery on the 25th of February. I was told the turn around time is 7-14 days. I’m now a whole month into this and they keep on telling me they’re awaiting feedback from the bank the money went into. Every time I follow up, I just get told my investigator is going to contact me and she doesn’t, then an agent will tell me they’re escalating the case but nothing comes from it. I’m honestly just frustrated from waiting. Is there seriously nothing more they can do as a bank???
