First national bank, my biggest disappointment

I have just called the call centre to understand what is happening with my balance because from last night to this morning there is a R250 missing from my available balance. I get through and speak to a Palesa. 1st of all her energy wasn't on par And I could tell she wasn't willing to assist me. I asked her the question about my available balance and she said I should hold. I don't know what I was holding for but I held. Over 20min went by with me on hold listening to music then all of a sudden my call was dropped. I called back and I knew I was going to ask for a manager but immediately once i got through to someone after the queue music my call was disconnected again. So money is missing from my account, I try to find out what is happening, I follow the right channel and make the call to get answers but I get mediocre service, I am at another financial loss because now my airtime is being wasted for nothing and I am being inconvenienced as well because it is my time that is being wasted and the distress of money missing from my account is not being resolved. I have never had a problem with fnb and I have always had faith in them. But today my loyalty is being questioned. How likely am I to recommend this bank after such ridiculous service? Unlikely.
