Don’t be friendly with account officers who have access to your money.
You can give them money once in a while for rendering services that ease your business processes, but do not cross the line of familiarity.

I had an account manager who used my funds (In my corporate account) for proof of funds to get a visa to the UK without my approval.
After getting the visa, she began to use her wiles to get me to give her 1000 pounds.
I refused.
When she was travelling, she still took the one thousand out of the account.
I had to report her to the bank to get my money back.
When I did that, all her colleagues felt I was mean because, according to them, she was my friend.

Let me say a bit more about this.
You don’t need to know anything about your account officer’s personal life. (This lady suddenly started telling me unsolicited sob stories about her children’s school fees, her house rent, and her husband, who was stuck in a foreign country and needed financial assistance, etc) I ignored, but by doing that, she opened the door to empathy from me, so that when she did what she did, I didn’t escalate it as I would have done if I didn’t know her situation. I only called her and told her to fix the issue immediately
Sometimes you will need your account officer to fund your personal account from your corporate account when you are out of the country and in need of money. You will have to send him or her an email to this effect. Always ensure you copy the branch manager in the mail
Account managers help you with unconventional transactions depending on the volume of money you are moving, the pressure of time on some deals, and the issue of the crowd in the bank, where you will be given priority. It is okay to be grateful for this, but tip them officially and keep it professional.

Don’t ever become “friends” with your account manager, and if you have an account manager who is a friend or a wife or husband or sibling, please move your money out of that bank.
People leverage relationships to do you great harm.
If you are not familiar with them, they won’t touch your funds because they know you will escalate it to the bank immediately, but once you have a relationship with them, they know you will be constrained from escalating it beyond screaming at them or making threats.

Some account managers keep it professional, while others will call to beg you for money. Some will ask you if you have a phone you are not using anymore to give them because their phones are faulty, etc. If you have to request a change of account manager, please don’t hesitate to do so.

A friend of mine married the person whose account she was managing, and it is true love, so this is not an indictment of all account managers

A couple came to me once to solicit financial help.
The wife was a banker
The husband was a businessman
The husband needed some funds for a quick business, and the wife liquidated her uncle’s 50 million naira fixed deposit for the husband to use for the “quick business.”
The husband did the business and lost all the money to fraudsters
The uncle had no idea that his money was gone
The couple wanted help to raise the funds and return them before the uncle would become aware of what had happened

I got a message a few minutes ago, a woman whose husband works in a bank said her husband begged her to open a fixed deposit account with his bank, and she did so.
She said she did this to support him in a way because he was under pressure to bring in fresh deposits
Six months later, she said she saw an alert from the bank
The alert was for two million naira
She said she started wondering what the money was for
When her husband got home that day, she then informed him that she got two million Naira alert from his bank and was wondering if she needed to call the bank and ask them where the money came from.
She said her husband said, “I liquidated the fixed deposit you had and borrowed 18 million out of the fund to meet some pressing needs. The two million naira was the balance.”

I have noticed that it is always those who are close to you or have a relationship with you who take advantage of the relationship they have with you to defraud you of your money if you entrust your money to them.
Strangers have no leverage on you, and they will largely leave your money alone, but once you allow them become familiar with you, they can also take advantage of that friendliness to defraud you.
