Not sure how these companies stay in busines

I thought using an engineer to oversee and handle the laying of our slab / flooring would ensure that I have the job done properly.. would have hoped at least it would be level. (was told by Walter a self leveling screed would fix the problem.) (Payment Terms & Conditions: 50% on acceptance of quote and balance before the floors are laid) Estimated Rand Value - R150 000.00 - once the bulk of his money was paid to him he had no further interest and moved on and I was left an unhappy client.<br> [URL Removed]
