Bad service and customer service

I am very disappointed of the service I received from this service provider. I have tried so many time to ask him for my refund but he kept on changing reasons as to why the service was not provided according to the agreed and expected standard. This service provider was supposed to do some deep cleaning for my house. The furniture was not moved, windows and curtains were not properly washed, When I asked for the refund he became arrogant and I have proof of the services that were not done properly.
