Realising of my money

My account has been locked by standard bank ***** department for over 3 months, they ask for proof of transaction and affidavit which I provided when i asked how long will the investigation end they said 6 weeks and what's annoying is that they are no *****ulent activity on my account hense I told them am trading with binance trading platform, I have been trying to communicate with my banker but I get no response. At this point I just want money then close all my accounts with them, and how can they Locked my account but still deduct monthly fees.
