Customer Care - Poor Coordination

Co-ordination is very poor between the company and clients. The installation was yet to be done and already I had an issue as no prior appointment was made. Before you visit a client for an installation a prior arrangement must be made. In my case I was given a call by the installer whilst at the gate and had to turn him back because I had a meeting elsewhere. Still no arrangements were made, when I whatsapp'd, I was told he is coming on that day, really thats not professional at all.
