Dear Harry: Back in March, we smelled gas in front of our house. We called PGW, and they came out, fixed the leak and left.

The next day, several concrete blocks caved in. When PGW returned, they attributed it to a water leak. The Water Department came out and found no leak. Since then, I have called PGW and the city over and over with no results. The situation is dangerous, and I don't want anyone to get injured and cause me further problems. Now one of our streetlights is out, so I'm worried sick and losing sleep. As you can guess, each one blames the other and nothing has been done. There has to be some way to get this repair done. Help!

What Harry says: Because this was a hazardous situation that needed immediate attention, we decided to act on your behalf rather than wait for you to act on our recommendation. The city and PGW got on the case immediately, and they now have the caved-in concrete removed and the hole refilled. The concrete work was promised to be completed in the next week. What took you so long to contact us with a situation that was a lot more dangerous than just a hole in the ground?
