I have been living as a subtenant for last one year. I was paying 'Nebenkosten' of CHF 125 every month. It was stated in the contract that I have to pay for electricity and water cost by myself in the end of the year.
I will be moving out at the end of this month..
Now I received an email from the main tenant that I need to pay electricity bill (which was fair price) + nebenkosten of about CHF2000.
I am shocked since this was never agreed upon.
Also, as a side note- the main tenants have really been acting as a**holes as first they wanted to kick me out in two weeks as it is a mobiliert.
Then when I asked them to use my deposit as a last month's rent-they agreed on the phone and now in the same email mentioned that I haven't paid January's rent- I should pay it immediately and the deposit will be returned after inspection of apartment (okay, fine.. but I am pretty sure they will use my deposit to deduct the above mentioned nebenkosten)
So now I am stuck with a bill of about CHF 4000 in the end (rent+electricity+nebenkosten)..oh and of course the rent for the new apartment.
