POOR TREATMENT

I am disappointed about the service of this bank. I've been its customer for may years but my account was frozen without any communication, and I realized this while I had already filled full tank of petrol. I was treated like a ******** and I was later informed that there was a private legal dispute. The issue has been resolved and Court Order emailed to its Legal Department but still my account is closed. I tried to call Legal Department but Consultants explained that they are not allowed to issue its contact number. I need my money to be released and I scared of wherether it is still available or not because I don't get any response
