Merrick Bank They closed my account without any notice Old Bethpage, New York

I am a active duty service member currently serving overseas. I originally had a account with Plains Commerce Bank but was bought out by this company, Merick Bank. They immediately notify me that my account was closed and will not be reopen since I was overseas. I tried to call the company, which was difficult due to the time change. Once I was connected to a representative, I was told that a letter would be mailed to me stating why my account was close.
I was never late in making my payments via web bill pay through my bank and always paid above the minimum balances.I feel that this company is fraudulent and should be thoroughly investigating for its corrupt practices. I have filed a complaint with the BBB against this company. I would like some resolution in this matter because there are several service members who also have accounts with this company and are having similar problems.
Thank you
