We regret if you experienced difficulty due to the conditions you reported.

Please be assured that customer safety and comfort are New York City Transit’s highest priorities. All stations are scheduled to be cleaned and disinfected, and station cleaners are responsible for removing litter, emptying trash receptacles, and disinfecting unsanitary areas upon detection. Stations are also routinely inspected and baited for rodents as necessary. In addition, some of our stations are hose-washed with high-pressurized hot water.

In response to your e-mail, we will continue to inspect all stations and adjust cleaning coverage as necessary to ensure a proper environment for our customers.

If you have further station-related questions or concerns, we ask that you contact us at (718) 330- 1234, from 6:00 a.m. to 10:00 p.m., seven days a week, regarding this type of issue.

We take the concerns of our customers very seriously and thank you for having taken the time to bring this matter to our attention.

IT BEEN ALMOST TWO WEEK THAT WE DONT HAVE HOT WATER OR HEAT IN OUR APARTMENT, PLEASE HELP

MY GRANDCHILDREN LIVE IN A TWO FAMILY HOUSE WHERE THE LANDLORD TURNS OFF THE HEAT AT 10PM SO SHE CLAIMS. THERE ARE CHILDREN IN THIS HOUSE WHOSE AGES ARE 8, 4, 2, 1. THESE BABIES ARE COLD ALL THE TIME. SHE ALSO DOES NOT TURN ON THE HEAT IN THE MORNING WHEN THE OLDEST NEED TO GET READY FOR SCHOOL. THIS IS A DOWNRIGHT SHAME. SOMETHING NEEDS TO BE DONE

I would expect the City of NY's own 'Mayor's Office of Film, Theatre & Broadcasting' to have a better protocol for productions shooting in our boroughs, than using 'packing tape' to attach notices to poles.
Particularly that these are newly painted and installed poles.
These are for the currently shooting 'Blood Ties', this is on every pole for 4 streets I have passed by...
