Alfa Concrete Walls - Really disappointing and frustrating!!!!!!!!!!

Absolute poor service! Accepted the quotation and paid 50% deposit. Arrangement was made to start on site at 9 am for the installation. It is past 11 am and still waiting patiently. Please re-consider using Alfa Concrete Walls that can't keep to timelines nor communicate with their customer. Really disappointing and frustrating!!!!!!!!!!
