FNB Bank ********** activity with my account

I don't know what FNB has done to my account. I was currently away and had no access to my account or calls. They tried to call me but I was not available as I was out of the country. Now to my surprise I cant even make payments, they have taken it upon themselves to block me from accessing my account without even communicating. So frustrating, they act as if they own the funds in my account. Bad customer service. Bad bank qill nevwr recommend anyone to use them.
