Missing Payment and no client service.

Most Frustrating bank and client service sucks. I am struggling with a missing payment that was made the 1st of April. After several phone calls and secure chats my problem has not been resolved. My money is missing and every follow-up call I make I need to explain every single detail over and over again and again. Follow up calls take more than an hour and then still nothing has been resolved. I don't know what to do or how to resolve this problem. Telling me my case number has been resolved after I am still waiting for my call or email I have been promised and I never got is super frustrating. All I know is I will never recommend FNB again
