I had a leak from the toilet in a 1 bed room Apt. As per contract they are suppose to come in 24 hours. I was told they will come next day between 8 AM to 8PM. At 6 PM they called and said they will not be able to come and they are rescheduling it for the next day between 1pm to 6PM. They did not show up. No phone call, email or anything else. They did charge me $45 for the service though. Scary.
