Bad service/damage to property

In February I had a fibre optic line installed. Mr Zukile Malunga and assistant came to to the first stage of the installation. In the process they stepped through my ceiling and made a massive hole. He said he would pay and to date I have not received all the monies owed to me. He still owed me R443.00. I am at my wits end as he is a service provided for telkom/ open serve. Please assist as I am tired of waiting for my money.
