what if the person says that he has no money to pay icicidirect will icicidirect forget about those 50+ thousand
No chance of that happening, ICICI are worse than shylock the money lender in Shakespeare's "The Merchant of Venice", they will collect every penny. If you read the papers they outsource their loan recovery contracts to the worst company's who employ goons to threaten customers who default on loans. They are the worst of all the banks in this respect, citibank used to be number one in this respect but ICICI have beaten them and are quite ruthless.
See izzner its best you contact some legal expert, you really need to know the legal rights you have here. They would be in a much better position to advise you than us unless we have some legal expert here who can advise you. Maybe ashish can just ask him profile id : acatrader
Also get hold of a copy of the POA and agreement and read it to know what they are entitled to do on your behalf under what circumstances.
