Water Issue

My grandmother has been out of water for a whole 2 months due to arrears. We settled the delequent amount on the 2nd of December and they promised that the water will start operating as per normal. When we got home still there was no changes we went back and they promised the same thing. Since we were using a lot of money to go to and fro we decided to buy airtime and call the call center, we called yesterday and they said they will be bringing someone to resolve the issue and we were given 2 references but nothing has changed till today I just called them now and spoke to a lady by the name Nosipho which says that the people who were appointed to come said that they came to the property and there was a building built on top of it but nobody came. Tell me how is an old aged woman suppose to live without water for this long?
