Unqualified,unregistered and unskilled bussiness operator.......

The owner of this bussiness has changed bussiness names about 4 or 5 times and im not sure if he is has registered these bussiness names with SARS or any of the relevant authorities.His workmanship is terrible and once he is paid he is not interested in repairing any defects.I gave him a lot of work at my bussiness premises and at my house and it is literally all falling apart.The cieling he has fitted has fallen off hitting staff members and when i asked him for assistance i was told that the cieling should never have been fitted on a steel roof structure.I have paid this company in full for all the work done and there is no after sales service.It has also come to my attention that this is a pattern the owner of this bussiness is to take money and not supply the service or goods and he never returns when his shoddy workmanship becomes evident.I would not recommend this bussiness to anyone !!!!!!!
