Business account closed without prior communication

Iam so sad to write this review because I am frustrated by FNB business wing . I lost business due to loss of service and work for my trucking business so my business account has been dormant for atleast 3 months so the tracking companies they kept on debating my account even though the money was nt provided for but the bank continued to provide for the overdraft of these transactions so I received only single communication about my account being overdrawn then all of sudden the next communication I received is your account has been closed and you are handed over without even calling me to make arrangements. I dont know what is the job of private business banker but I just got a call from the lawyers already demanding a lump sum of money for the lawyers and the bank already where would I get so much money when the business in not functioning due to transport in breakdown. It seems they want to fix me more . I jave been banking with fnb for 6yres and my personal accounts are also with this bank for so many many years . My heart is just broken. Now they want R8000 plus where would I get the money and how did the amount went so much because if the debit order is returned the debit fee only is charged .
