So frustrated

My funds are blocked by capitec because someone reported ***** so it happened that they mixed up names. They blocked someone's funds who did not do anything, how can you be so careless like that with someone's money? I really don't understand, we were asked to send affidavit with the person who opened this case so we did but nothing has been done, they are sending me up and down when I call or go to the branch. Legal actions I will take if nothing is done by the end of this week because all of my bills are on hold now
