Southgate builders not worth it at all

The staff are disrespectful, not willing to own up, don't value customers and they and thier manager are ***** and definitely will I never visit the Southgate branch ever again... To think I have supported them so many times... What a waste of my time .. I get a 140 delivery charge, after they mess up and are rude to me for their own incompetence...my delivery charge is suddenly 280 and a staff member and what I assume to be his manger give me two very different stories as to why, I'm then told my delivery is infact 390... On top of their bloated prices.. the same rhino board I got elsewhere and many different places below 150 they want 350. Pathetic really
