Sent out a bill 3 days after it was paid! when called they said they were notified the day it was paid. Bill was not in collections but took it upon themselves to send out a collection notice anyhow!....this company is a scam.....they're hoping people are stupid and will pay their bill also! SCAM,SCAM,SCAM!!!!
