Landlord office works passively

Pros

Clear inside and outside of the Building.

Cons

The landlord office is not fulfilling its duties to tenants. It is unacceptable that the landlord office is not responding to tenant’s inquiries about lease. The landlord office has a responsibility to promptly address, but I have been waiting already for 1.5months a feedback from the landlord office about my request regarding to lease agreement. I have emailed them, called them, but still have been waiting. Even it’s a big problem to reach them out by phone. No response.
