Toelichting op de werkzaamheden:
Advocaat/Jurist gezocht

I am having an issue with the Painter that I hired. Who took 50% advance and didnt completed the job. Now he is not answering or responding to our call.

The whole job was agreed to be done in 2600 euros with 9% BTW.

I had paid him 1300 Euros in advance which he told me that the invoice would be given at the end. But 600 has been paid as a cash and 700 paid as online.
He had signed on a paper that 600 cash has been paid along with his signature.
