Lame service from FNB credit card ***** invistigation

If you are going to report ***** with FNB Credit Card Invistigation and you are informed on certain days the invistigation is going to take, forget about getting any feedback from them, this is the bank for crying out loud, some of the agents are so *********** and dont care, we are given numbers to call them and yet they will send you from piller to post and still come out empty,its almost like they have commited that ***** to begin with, I was expecting more than the lousy treatment I have been getting from them. Do we always have to go via this route to get your attention? If thats the case, Hellopeter should be asking "How can we help you"
