Be very careful when paying large deposits with this contractor

Received a quote - paid 80% deposit. Work was of the worst standard. Erecting a small Clearview fence. Owner admitted work was substandard, and will redo. Next day left 2 workers - never on site. I helped the workers to erect fence. To date no ******* removal. Gate not fitted. Fence not painted. Excuse after excuse. Also no refund
