Unbelievable actions from Electricity Department

A few months ago the Department of Electricity installed electrical supplies to a newly built house in my area of Bayview, Strandfontein Mitchell's Plain. During this process they removed the tar and sand from infront of our house and failed to replace it and compress the sand again, thus leaving a big hole and loose sand in the pavement/ front section of house. This causes my car to struggle to get into our driveway due to loose sand and having to park over an untarred pavement/ hole due to them failing tar the area which they removed. I have contacted the Department on numerous occasions, and have been promised many things, never-mind all the phonecall attempts which goes by unanswered or when I get put through to almost 5 different people on one phonecall. Completely disgusting! My reference that I have been given and is ***. Please replace the tar that you have removed infront of our house and compress the sand infront of our driveway that you have loosened due to digging it up.
