City of Salem, Public Works Dept.

I was on a long vacation and arrived home 3 weeks after my water bill was due. I found my water had been shut off. I paid for the bill over the phone immediately and was instructed how to turn my water back on (at the water meter at the street). I followed the instructions but the supply was not returned. I called the Water Dept. back at 4:50 PM. I was told that all customer representatives were busy and that my call would be taken in the order that it was received. At 5:15, I took the computer’s suggestion and selected 1 to give my phone number and await a return call from the customer representatives. After selecting 1, I was told that their voice mailbox was full and it disconnected me. I then called back to be told, again by that computer, that the office had closed at 5 PM and that I was to call back again tomorrow. So, I have no water for this evening.
What bothers me the most is that I did get a bill saying I had missed a payment and that the current payment along with the past due amount would be due on June 4. So I called up and scheduled an ePayment for June 4. However, my water was shut off a week PRIOR to this. They never sent a letter to me nor called me to notify me of their intent of discontinuing service. Instead, my roommate found a letter at my house and a notice on my door knob. They had my phone number! They asked me for it! Why didn’t they bother to call me for something as serious as this?
If this was a bonafide business, they would be «out-​of-​business» with service like this. But, they have a monopoly and all I can do is Unilocal*them.
