Thank you for your help in advance. I am handing over the apartment in Zurich canton and have done everything by the book. I sent the letter in advance for September handover. The agency responded with a contact number for the handover person. So I did this even form July 2023:
1) I prebooked the professional cleaning with insurance on the 26'th of Sept 2023 and with their presence on site at the handover date on the 29'th of Sept 2023.
2) I prebooked the handover with the contact person from the agency on the 29'th of Sept.
3) I wanted to be extra sure that all goes fine so I prebooked also a help form mieterverband which sent a person on the site on the 29'th of Sept that also spoke english, as I speak german at only A1 level.
All good and nice started at the handover date, we all met there and the inspection started. I haven't seen this in my life to check all small areas with extra light and carefulness and make the cleaning person do more polishing on the spot, but from what the mieterverband person told me it was normal. Anyway, after 45 minutes of inspecting things the agency representative concluded that the cleaning person didn't do a good job in specific areas (dust on top of balcony doors, and storen on the windows needed more extra cleaning and some calcar in the WC). The person from the mieterverband did his own assessment and concluded that indeed cleaning company didn't do a good job so we all noted down the things that would need new cleaning, as I had a guarantee.
We all agreed verbally that the cleaning company would redo the cleaning during the weekend (30 Sep and 1 Oct) and then I inspect the apartment during the weekend and then me and the agency representative will meet again Monday 2'nd of Oct (the mieterverband person would be on holiday starting Monday and it would be too late to book another one).
Things went south when the agency representative didn't want to sign anything (she said she is not allowed to sign) and didn't want to commit to an hour for Monday saying that she will call me on Sunday morning (today) to set an hour for Monday. Even the mieterverband said he never encountered such behavior and eventualy agreed that I will be called on Sunday and then will see when to come on Monday. I also had to get the keys back and now the keys are with me.
Cleaning company finished, I need to go today Sunday to inspect and pay them and get the spare key from them, all good on that front.
The problem is that the agency representative didn't call me back. I sent a SMS, I called but nothing. I understand it's Sunday and it might be problematic so will have to wait until Monday morning.
Now the question: The mieterverband person said that worst case scenario is that they don't have a new tenant already and they might want to trick me into paying Oct rent as well and delaying the key handover. He advised me that if I have no answer by Monday morning I need to go to the agency myself with a key handover paper and request them to sign and take the keys by Monday 12:00 or it is too late after. TBH I don't want to force anybody to sign anything, would not be in any way ok doing this. So I'm looking for an elegant way out.
What should I do? I would prefer to solve this quietly an without hassle, that's why I did all these things and it's not my fault the cleaning company didn't do a good job from the start. I understand maybe I should have double checked what the cleaning company did one day before handover but I put my trust in SWISS quality (it's my first handover and I'm foreigner).
My plan is to wait until Monday morning, try to call the agency person a few more times until then and if not then on Monday morning call mieterverband again for another confirmation that I really need to go in person to the agency and give them the keys.
Any opinions?
