Bad Apartment manager...bad!

[John Stokes]

So...need some advice.

My 17 year old daughter is living with my mother...long story.

Point is..they just rented an apartment, 1 year lease. Been there about 2 months now. The on-site property manager is a woman of Spanish descent, so are my mom's upstairs neighbors.

The upstairs neighbors are exceptionally loud and rude about it. I don't necessarily think it's the adults that are rude, it's the lack of adults. The mom, as I understand it is a single mother and hey kids are babysitting other kids? Something like that...point is they are EXTREMELY loud. And when my daughter bangs on the ceiling to signal them to calm down...they stomp back. My daughter has gone up and politely asked them to calm down...they stomp louder.

I went to the office and very sternly complained...only to hear them make excuses...

"they do live upstairs so you have to expect some noise"
or
"We have notified them...it's not our fault"

Just yesterday, my mother went up and complained. The neighbor (a Spanish woman) and the manager (another Spanish woman) and my mom all talked. (my mom is a Vietnamese immigrant---before any accusations of racism start flying around) When they spoke, according to my kid, the 2 Spanish woman joked and laughed and then told my mom they've been renting for 10 years with no complaints...so sorry.  

Needless to say...I'm not happy. Suggestions?
