Rentalcars.com unfair no show fee

I had a similar situation 2 years ago with a delayed flight to Barcelona where the Rental car office was closed when my flight finally arrived. I hadn't tried to contact either the booking company (ebookers) or the rental company (Goldcar). When the rental office opened the next morning, the company wouldn't honour the booking and wanted to charge 3 times the original price for the same car. While I was waiting at the desk I went directly to Goldcars website and booked the car online for £10 less than the price I had originally paid. I then carried on with the booking at the desk.
Once home I emailed ebookers and they agreed to refund the money I originally paid. Although it took 3 more emails to get them to follow up on this promise to pay, eventually they did.
One thing I would say, because the booking was in October the price was a lot lower than Andy paid (in the 40-50 Euro range)

Anyone else having the same issue -

Rentalcars.com will normally reject a claim on first contact, its their way of closing customer services cases quickly. If you contact them a 2nd and then 3rd time they will usually give in as its no longer cost effective for them. Most car hire companies do not charge rentalcars.com for the hire unless its used, so if you keep asking they will normally refund as a goodwill gesture despite the terms and conditions.

If you do have phone records to show you tried to contact them at the time off pick up they will refund you, as they realise that is probably their fault
