worst time for bad news bank

so this useless bank decided to make a double deposit in my account, they neva called instead when i deposited money recently they blocked my account. i had to use a lot of airtime to get them to unblock it. and they told me i have to pay 1500 that they double paid me on 02 March..................what nonsense. and trust me they took the 1500........................such inconvenience. i am cutting that card.
