I am really scared of car renting companies based on my bad experiences previously. I try to be as cautios as possible. Also I cannot afford to lose any “extra” money for risks which I could avoid. Please please help me.

Is it normal that you have to pay 300€ deposit when you want to rent a car for a week?

After a long searching for the best and safest company, I found Car4you. But I read some bad views about that they do not give the deposit back.
Also, did you heard anything bad about this company? (Of course I will pay for the FDW.)
Your help is appreciated.
