DDGBS Ltd Building Company review: Scam and fraud done by a builder

This builder offered a reasonable quotation to tile my garden.
He made some extra cosmetic work which indicate that this work is included in the quotation.

Did not provide any contracts.
Did not want to give any receipts
The work he done is a cow boy work
Hide all the material costs, did not talk about any additional fees.

At the end of the work he serve invoices with five times double the quotation
And proceeded to court with it.

This company is a scammer.
