Bill paying fund

Hi, this is the last place I would ever think of posting.
About 2 months ago a telecommunication provider took 600€ from my salary, because of a mistake they made in 2011 by not clearing my account.
After that I sold my car and deposited 650€ on my account and they took 600 again, because, again, of a mistake on their side.
The thin is that, since they are in the process of bankruptcy I will probably never see the money again.
I'm in the process of suing (i have also all paperwork) but it is costing me money I don't have.
So now I'm without a car, without money and my rent wasn't paid for in 2 months.

I sold pretty much anything and this is the last place I could think of.

Well, if you could help me get through this 3rd month of hell I would really appreciate it.
