My son purchased a house in Del Sur, Sandiego, usa. Once after rain he noticed stagnation of water at the end of his verandah. He complained to the authority verbally showing a photograph of the condition. After two or three days person came, measured the portion of stagnation and asked the appropriate time they can come. Actually they came net day with all the materials they require for repair. They did their job and informed that they will come after some time when the finishing work can be done. They came and did it.
