Poor Customer Service

I have been a loyal and dedicated client of FNB since 1991, I have never given them any reason to doubt my loyalty , I have conducted all my business with FNB over all these years. I have grown together with the bank and has I have progressed so did my buisness with FNB. I am very dissapointed at the fact that after all these years as a dedicated and loyal customer I am refused a home loan without any just cause. This is the first time I have actually requested FNB for assistance with a loan. MY CREDIT RECORD IS EXEMPLARY WITH FNB. This to me is a sad situation. I am truly dissapointed. FNB slogon 'HOW CAN WE HELP YOU' , I dont understand, a client of 24 years loyal service request your help and you refuse. Thank you for nothing.
