Disappointed in the treatment of loyal customers

I am an extreamly dissapointed customer. I have been banking with FNB since 2013. In Feb 24 they sent me an email stating they are closing my personal accounts as I do not fit their "risk" profile. I am a standard full time employee earning only a salary into my account . I have never once missed any fee payment or credit debit order from FNB , yet they treat me in this manner. After this email they still offer me new credit options. I loved this bank but if this is the way they treat loyal customers I recommend people to rather go elsewhere when choosing an account you never know when they might suspend your account for no apparent reason.
