F.N.B is a threat

Hunnnnnnnn F.N.B has started again with me, last year 10th of may, 2019 my account was frozen and when i went to bank they told me that i collected a money gram and the person reported the transaction, i called the person who sent me money and the case was resolved by the help of hello peter, after i gave f.n.b all the necessary documents which they requested for, they released the account back around july or august 2019 not so sure of d exact month, now again on 10th of march, 2020, my account was frozen again by f.n.b. i called to confirm what happened they told me that it was because of the issue that has been resolved they are taking me back to...... PLS HELP ME AGAIN am tired of the threat by F.n.b. every year.... if i had any hidden thing with the account, i wouldn't be using the acct till now. While is it that suddenly f.n.b blocked my account again? After all i didn't go into this person account, he went to money gram to transact the money himself without threat, while is f.n.b threatening me because of this?
