Bad customer service.. holding funds unnecessarily

The worst bank ever. I made a payment to my husband's account wanting to send money home. Hello Paisa put his account on hold requesting that I send the documents and pops that the money was from me and it's purpose. It's been over 4days now we've send the documents they requested now they don't respond and still don't answer their calls to unhold the account. That money is needed to cover hospital bills and if anything happens am going to sue hello paisa. If it was ***** why don't they answer calls and explain.
