Horrible service including ******* of my money

My name is Sisanda Msweli, I had a horrible experience with this company after I employed their services of shopfitting for my renovated house.After I paid them as per our agreement of the contract they only delivered 2% of the work and failed to deliver the rest but they have refused to pay back my money to this day, I need assistance to get my money back as they are such a horrible company who have withheld a large sum of my money for long now.
