In this case, you can only wait for the investigation to be resolved. I would like to tell you that if you have not done anything wrong, don't worry. But I would be worried if I had not done anything wrong and my account was frozen.
Yes. Waiting for the update from bank. Its really pathetic without asking or informing before suspending bank account. I have all the receipts and history of local bitcoin chat. If someone asked me amount it i will handover and easily find the scammer who did this. Better use zebpay or unocoin.
