Discovery bank must just close doors ,if they are gonna take our money and run

Worst experience I’m facing,my account have been blocked due to preceding ***** case,I called them several times since i have been waiting for their investigator to call me ,finally when i manage to get hold of them they tell me they have completed the investigation and I will not be getting my money .How was the investigation conducted because I was not contacted and I was not notified about any amount and payment that was *****ulent
