FPL / bad service

Today I was feeding my daughter (4months) when there was a knock on the door. I immediately headed for the door and looked out the peephole, no one was there. I put my daughter down preceded to look out the front windows. I opened the door and seen a sign for disconnection. Then my power went off. The guy came to the front and told me he knocked and thought no one was home! He said once I pay it he would send someone out to reconnect it. My bill would be 200 dollars and they never disconnected .it but today for 80 they did. I could have paid him right there if he waited waited for me to answer the door. I jus got the final notice today, smh.
