They surely have other problems right now than your 200 euros ...
They have
no problems at all anymore once the insolvency administrator has taken over the helm. Put simply, his course of action is as follows: where the company is a creditor, collect what you can; and where the company is a debtor, contest everything first – including legitimate counterclaims.
Example: the company owes the customer 300 euros, the customer owes the company 200 euros, then it is like this:
The customer thinks: 200 minus 300, so I don’t have to pay them anything and still get 100 from them;
The insolvency administrator demands the 200, which he wants in full. He first takes care of himself – let’s say his fee for the insolvency administration is allocated to this income as 40, the remaining 160 goes into the insolvency estate. Let’s assume the insolvency estate totals four million, and the sum of creditor claims is twenty million. And let’s also assume that the customer’s counterclaim would be recognized in full.
Then the calculation looks as follows: the customer pays the company 200, of which the administrator takes 40, only the remaining 160 are available at all for the counterclaim; he settles the counterclaim with 300 x 4:20 = 60. Net, the customer has therefore paid 200-60=140 instead of, according to his calculation, 200-300=100 received.
The right-of-way rule is unfortunately clear: law before reason, and therefore a simple subtraction calculation "they owe me more than I owe them, so I get something" turns into a point calculation "they have less than they owe everyone, so I still pay up" :-(
