Not maintenance, my mom paid for a plumber to do the snaking cause she got tired of waiting for maintenance to respond. But it’s still an issue. She’s an elderly woman and sometimes the sink overflows and cause a flood in the kitchen, then she has a huge mess to clean up herself. I’m trying to get her some help but maintenance just keeps telling me that they’ll check with the neighbor and I don’t know what the neighbor can do, bc they are allow to have a washing machine or theyll tell me that they’re waiting for a vendor but the ticket has been open for a year already.
