The installer finally responded to our letters, albeit in quite a colorful manner:
Dealing with the problem of criminalizing a fellow expat?
He accused us of making false allegations and seems unable to distinguish between a private exchange of opinions and criminal lawsuit accusations.
His terms for a clarification meeting and a fair solution?
A tête-à-tête at his lawyer's office. As for resolving the issue, his "constructive" solution boils down to us paying all alleged debts and any legal fees incurred or expected.
His opinion about community support?
We informed him beforehand about our intention to seek community support, asking if he was on board with it as we did not want to escalate the situation.
He just laughed it off in his response, saying, "They'll die laughing!"
Here's a short summary what we answered him to this, aiming de-escalation:
We pointed out that, as mentioned in his letter, he wasn't directly dealing with the lawyer. Which might mean he's not fully informed about the situation.
We respected his right to fight for what he believes is his, but pointed out that civil court, not criminal court, is where these matters, if at all in court, has to be handled.
Fellow Expats, it has already been a lively and helpful discussion, thanks!
I really appreciate all further comments and ideas.
