DON'T USE INTERRENT! (Faro) They are rude Scammers!

DON'T USE INTERRENT EVER!

We did got scammed at Interrent (Faro) a little bit even though we were very careful:

-We checked the car thoroughly for damage, BEFORE signing their form. And found multiple small scratches. (they told me it was not possible to sign AFTER checking the car, so I just walked to the car with the papers. Don't let them trick you! you can ALWAYS sign AFTER you agree on what you're signing.)
-We mentioned that we would return the car FULL, which they didn't like but agreed to in the end.
-If you already have insurance DON'T let them trick you into getting more insurance because you'll be paying DOUBLE. The only thing they said that was true while trying to convince me I MUST?? get their insurance to be insured was that IF something happens, they will charge you the money from you credit card. WHICH IS FINE. You're insurance will pay you back afterwards because that is wat insurance does!
-The women got very rude and annoyed because she wasn't able to sell me any extra's. I stayed polite and calm during the whole process which might have gotten her more angry because she finally understood I would not get tricked into anything. (no bonus for her because she couldn't SCAM me).

The Scam:
When we handed the car back the tank was 100% full, we filled it down the road from Interrent.
On the Invoice I received later they charged me 2/8 of the full tank. Not the end of the world but still ANNOYING.

DON'T USE INTERRENT EVER!
We had a tough start of our holiday because of the experience of getting the car, even though I didn't feel that upset.
