DISCONNECTED SERVICE, THEIR MISTAKE!!

I called the morning of Jun. 1,2020 to ask the why my electricity is disconnected. I clearly called them on 2 occasions to cancel my disconnection notice since I had not yet moved into my house. They told me after I waited over an hour being transferred, that they will connect me in 1 or 2 hours top. It is not 5:15 p.m I have NO ELECTRICITY & they are not answering. I am so humiliated after paying them $218.00 balance that was suppose to be made in payments & they still haven't taken the time to connect my service. It is outrageous. I have been a loyal customer for over 5 or 6 years.
