We hired our car through Alamo in April and booked the all inclusive, all singing, all dancing insurance. DH went to pick the car up - and was fully aware that there was nothing else to pay. He was asked to sign in 3 places for them to release the car, which he did. He was ONLY asked to sign to accept the car - nothing else was mentioned - and he assumed that as everything was pre-paid for it was nothing more than that. (If you knew my DH there is NO WAY he signs for anything without checking everything in triplicate!)
On our return they had charged his card £60 - we eventually found out that one of the so called "car acceptance" signatures was actually a signature for breakdown cover!!!!!


When we raised the query with the TA and CC people and said that we regarded this as theft from us, because he had signed the paperwork there was nothing we could do.
Expensive lesson learnt on our part.
Hope you manage to get this sorted.
