Nonsense excuse of a bank

Worst bank I have dealt with, I cant even say I am using it cause I last used it in 2018 but now they are listing me and handing me over to their lawyers because apparently I owe them money or my account is overdrawn.... for an account I have clossed yesars back , they swear I never clossed it though, I have tried countless of time to contact them regarding this matter.
