Rent a Car - excessive car insurance add on without prior notice and refusal to return insurance deposit. Internet

We ordered and payed on line for two car rentals each for two weeks. We paid $639.00 US for each car up front which we believed included car insurance. On arrival we had to pay approximately $1140 in addition for insurance. We were told that our Visa or any other insurance we might have was not valid.

Later reading the miniscule type font it stated had we had a statement from a bank, Visa, or other showing we had insurance we would not need additional insurance. In comparison, after my sons picked up the cars having paid the huge extra cost I went to a local car rental, Economy Cars in San Jose, I was given a total price of $1140.00 US for two weeks for a similar car.

Then despite having paid the high insurance rate they refused to refund the $500.00 US insurance deposit saying we had not notified them of an incident which caused very minor damage to a rear light. No where in the contract nor when picking up the cars was it stated that this was a requirement. The people in the rental office got hostile and said that they would call the police if my son protested the excessive charges and the refusal to return the deposit.
