Poor workmanship, delays, and lack of accountability

I requested that screeding be done first by the Durban North branch and was quoted accordingly. The job was completed, however the finished product is not up to a standard that allows vinyl flooring to be installed as promised. The screed is uneven, and instead of taking responsibility for the poor workmanship, the company is blaming the subfloor. As a result, I am now expected to cover additional costs to fix an issue that should not have occurred in the first place. Communication throughout this process has been extremely poor, with ongoing delays. It took approximately three months for the manager, Danny, to eventually come out and inspect the finished work. Overall, this experience has been very disappointing. Due to the poor workmanship, lack of accountability, delays, and weak communication from the start, I would not recommend this branch for future work.
