Mirna R.

I have booked a car by using their online website, I was supposed to rent from Europcar Ponte Nuovo (RA) Italy, for one day.
I checked if my debit card was accepted and their website (you can verify this) said yes. They have immediately withdrawn about 80 euros from my account.
When I visited the local agency to get the car, the clerk was in a hurry because she had another client after me. When I paid, she tried once to use the card, then she said it was not working. She quickly asked another customer, while suggesting to ask rentalcars for my refund. She didn't even greet me.
The overall story took about 5 minutes.
I have contacted rentalcars, and they replied they can only refund half of the amount.
Basically, I have wasted about 30 euros and didn't have the honour to have a second attempt for my card.

The customer service of rentalcars has contacted the local agency and the lady has promptly replied that mine was a prepaid card. I have a bank account and this debit card was emitted from the bank. It is not prepaid, since their website had withdrawn my money.
Keep in mind, they accept a card when you book, but then refuse it when you go to the agency, then you waste the amount you paid.
Update.
The customer service suggested to contact them today, after the end of the "supposed" rental, and this is what I did. But I have just received this email:

Basically, they say I have informed them too late ( so, yesterday was too early, today is too late, the length of the rental was 1 day, so.)
