The situation is next one. My previous employer made a mistake and instead of deducting 300 EUR a month for my train subscription, they were paying me it extra.
I treated this amount as their compensation for traveling and several times contacted HR that I don't see a deduction.
I left this company and finally they found the mistake. Right now they are asking me to pay around 5000 EUR back. I can not and don't want to pay this amount in one time. I tried to negotiate it to pay in smaller amounts. They are fine that I pay it partially but asking to pay in bigger chunks.
Today I got a letter starting with "Politely I ask your attention for the following..." and it comes from their lawyer. I assume it might come to the court.
I have a small hope that someone could give me thoughts about my rights. I also applied for legal insurance but it will start only in 3 months.
